This started in Dapper, and continues in Feisty, but not in Windows XP.

The mouse moves erratically around the screen, any icons or links that it passes over, it opens. I've seen many references to this error message, but no solutions. I've tried USB mice, but they give other errors, which are under investigation already.

Thanks for taking the time to report this bug. Unfortunately we can't fix it, because your description doesn't yet have enough information.

Please include the following additional information, if you have not already done so (please pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.

For your reference, the full description of procedures for kernel-related bug reports is available at [WWW] http://wiki.ubuntu.com/KernelTeamBugPolicies. Thanks in advance!

Thank you, I'm marking this as confirmed.

[buio (rb11520)]

One of quick workarounds for this is to turn off wireless in Network manager.

[Dianne Reuby (pramclub)]

This seems to have decreased dramatically in Gutsy - I have had only one occurrence since upgrading. I don't have wireless networking.

[buio (rb11520)]

Unfortunately, when the wifi is on, the problem occurs quite often. See attachment.

This seems to be a problem cause by typing - it has actually happened twice now just during typing into the comment box for this bug - both times causing the text to be highlighted, and subsequently deleted by the next key press! Also, the mouse appears to be clicking (and right-clicking) at random, and also moving slowly in a diagonal direction for up to a few seconds (either down-left or up-right usually).

After the problem has happened, I lose the ability to click on dialogue boxes or to raise certain windows, but some mouse actions still appear to work. The only wait to gain (albeit temporarily) full mouse functionality is to CTRL-ALT-F1 to a text console and CTRL-ALT-F7 back to my X session.

Not entirely sure if this bug I'm describing here is exactly the same bug, but I certainly seem to be getting the same errors appearing in dmesg (attached) as has been described by other people. Whether this be causation or correlation, I'm not certain.

[rebroad (rebroad)]

Futher to my last comment - after the unwanted mouse events have passed, any further clicking of the mouse (e.g. on the applet bar at the bottom of the screen to raise a different window), all clicks behave as if they were entered in the currently selected window, highlighting all the text in the currently selected window. (How would this normally be achieved?). In order to successfully click on the applet bar, I have to switch to a different console window and back again (as mentioned in my previous comments).

[rebroad (rebroad)]

I just noticed the 2.6.20 in the url of this bug. I should point out that uname -a reveals "2.6.15-51-686", so apologies if my comments are being put in the wrong place!

[Leann Ogasawara (leannogasawara)]

The Hardy Heron 8.04 Alpha series is currently under development and contains an updated version of the kernel. It would be helpful if everyone could test the latest Hardy Alpha release: http://www.ubuntu.com/testing . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. Thanks.

[Istrebitjel (madeingermany)]

Thanks, Leann. I have alpha 6 running from live cd for some hours now and have not encountered any mouse trouble.

[Leann Ogasawara (leannogasawara)]

Hi,

BC7333 - care to open a new bug report. The errors you are getting appear to be different than the original bug reporters. It's helpful to the development teams if bug reports target a specific issues against a specific set of hardware. We can easily mark reports as duplicates later on if necessary. In your new bug report if you could include all of the information outlined here: https://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks.

bigoperm - your `uname -a` output shows you are still running a Gutsy kernel. Please test with the latest Hardy Beta release - www.ubuntu.com/testing. Thanks.

Leann,

Thanks for the kind tip. Added new bug https://bugs.launchpad.net/ubuntu/+bug/206761

[armlis (armlis)]

Hi,
I think I know the same bug. The mouse pointer move itself to some of the corners of the desktop and frenetically click either left or right button while approximately one second.
I can add that the keyboard may seem to press itself some of the last "really key pressed".

Of course.. all possible actions which were met in the mouse path happens : software close, some other "open with", gnome-session stop etc...) all that depending on what's on your desktop at this time (and the icons or applet in your desktop corners).

All worked fine for several months ; I do apply all official updates as soon as they come and have just updgraded to Hardy as adviced here. (nice to meat hardy)
The bug began for me near the 2008 march 15 (after an update?)

# uname -a
Linux armlis-desktop 2.6.24-12-generic #1 SMP Wed Mar 12 23:01:54 UTC 2008 i686 GNU/Linux

syslog always says that à the exact time of "this event" :

[Matt LaPaglia (mlapaglia)]

This happens to me as well, i also have the ipw3945 wireless card. It seems to happen always at startup, when the desktop is first loading, but it rarely happens afterwards for me. I get the same error as armlis in my dmesg.

[Matt LaPaglia (mlapaglia)]

Sorry, I meant to mention I was using the hardy beta. This doesn't happen to me when I am running gutsy.

[Matt LaPaglia (mlapaglia)]

Does it matter that I have a synaptic touchpad but i'm getting ps2 errors?

[exactt (giesbert)]

This happens to me as well, i also have the ipw3945 wireless card. It seems to happen always at startup, when the desktop is first loading, but it rarely happens afterwards for me. Using latest hardy. This didn't happen to me when I was running gutsy.

[armlis (armlis)]

Sorry but i can't figure out why, but this bug has gone away for 2 or 3 days...
(I had a HardDrive disfonction that obliged me to boot on Gutsy Live-CD .. and what was my surprise : (without any mounted drive), my mouse gone away as discribed in here... ??? HELP)
I can't believe it. Would this be a material fact ? (I'd hope it would)

I really don't know why. This hasard seems so weird. (any kernel seems to be affected by this trouble)

 Leann.. how can I (we) help you ? (Material description ? WireLess ? I don't think so 'cause i'm not wifi equiped, but why not.. who knows... héhé))
Thank you anyway.

[Dianne Reuby (pramclub)]

For me, this seems to be related to the hardware of the mouse - if the cable catches on something, or is in certain positions, although I've tried several mice. Some days it's much worse than others.

[Matt LaPaglia (mlapaglia)]

Hm, when I use regular usb and bluetooth mice I don't seem to have any problem, it's only when I use the touchpad built into the laptop.

Maybe these are two separate problems?

[Matt LaPaglia (mlapaglia)]

Not to flood this thread, but this just happened to me after system startup (when it has previously only affected me.)

I opened up a 30mb .avi file into the default movie player, and when it fullscreened the mouse started jumping everywhere.

[Matt LaPaglia (mlapaglia)]

disabling acpi makes my touchpad work correctly at startup.

[exactt (giesbert)]

can confirm that "disabling acpi makes my touchpad work correctly at startup".
still this bug is a regression from gutsy.

[exactt (giesbert)]

this looks like a dup of #109326

[Matt LaPaglia (mlapaglia)]

exactt-
I would agree based on the "throwing away 2 bytes" part of that bug.

Also, I added "acpi_osi=Linux" in place of disabling acpi, and it makes the problem go away. No other devices seem to be negatively affected, and nothing weird shows up in dmesg.

[Matt LaPaglia (mlapaglia)]

any updates?

Hi, I notice a lot of us who have this problem are using a wheelmouse. In my case it is an MS Intelli 1.2A PS/2 mouse with product ID 63618. When changing the mouse the problem disappears. I have noticed that the cable to this mouse is more thin/slim compared to other mice. Perhaps this kind of cable are more likely to produce parity/syncronisation errors. Are your troubled mice also having a cable of a slimmer type?

[Chris Gitzlaff (chris-gitzlaff)]

I apologize if I caused any confusion with my previous post (2008-06-07).

My computer (Compal EL80) is a laptop.

The mouse that I am having problems with is a built-in touchpad but it shows up in /proc/bus/input/devices as "ImPS/2 Logitech Wheel Mouse". It has two buttons with a biometric fingerprint scanner between them. It also has a scroll area on the right side of the touchpad.

[Matt LaPaglia (mlapaglia)]

I've got the same computer as Chris.

This problem also occurs when I am opening up a folder with lots of pictures. The mouse is crazy until all the previews are loaded.

[exactt (giesbert)]

i just found https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/34501 . the mentioned option to add 'i8042.nomux' works for me as well as 'acpi_osi=Linux' . does anybody know the difference/up-/downsides of the both options?

also got a compal hel80...

[mrmaikel (michaelplucik)]

hi!

i also got a compal hel80 and the option 'i8042.nomux' isn't working for me but 'acpi_osi=Linux' seems to work fine!
is it right that i have to add

[code]
# acpi_osi=Linux
[/code]

to my /boot/grub/menu.lst ?

i'm using kubuntu hardy.

[exactt (giesbert)]

out of interest: what bios version do you have installed in your Compal Hel80? I have 122B.

try

lshal | egrep "(system.hardware.(product|vendor|version)|system.firmware.version|power_management.quirk)"

to find it out.

P.S. to set the option per default you have to add the option to line

# defoptions=quiet splash

which would become

# defoptions=quiet splash acpi_osi=Linux

in /boot/grub/menu.lst and then run update-grub .

[mrmaikel (michaelplucik)]

i have installed 028B.

i inserted to my menu.lst:

# defoptions acpi_osi=Linux i8042.nomux=1

and the problem seems to be gone.

do you all have the problem https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/123775 too?

[Chris Gitzlaff (chris-gitzlaff)]

I'm using the 123B bios on my Compal HEL80. I just installed it on Saturday. Prior to that I had been running the 122B bios since it was released in July 2007. The 123B says it is an ACPIEC fix, though there are no other details. It is only available on http://www.bizcom-us.com/support/, not on the main Compal support site, yet.

I haven't noticed any changes between this bios and the previous. I'm still running with "acpi_osi=Linux", though.

[Thom Pischke (thom-pischke)]

I'm having this problem in Xubuntu 8.04.1, PS2 mouse, no wireless card installed.

[Leann Ogasawara (leannogasawara)]

Beginning with the Hardy Heron 8.04 development cycle the kernel source package naming convention changed from "linux-source-2.6.xx" to just "linux". Going forward, kernel bugs should now be reported against the "linux" package. I'm removing the linux-source-2.6.24 task as this is already correctly reported against the "linux" package.

[Nicholas (nicholas-a)]

This is happening to me too. I'm using the latest *19 kernel. Its a PS/2 mouse. I have no WiFi cards or touchpads. It drives me crazy. The mouse randomly clicks stuff, in in one case, edited my email to gibberish :( I hope there is a fix soon.

[Leann Ogasawara (leannogasawara)]

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

[Nicholas (nicholas-a)]

I am interested in testing... cause I am desperate for a solution.

My Xorg.conf is modified by an NVidia driver. If I change even a single line on the mouse section, the display fails. I have attached my Xorg.conf file for details.

Could you tell me how to get and install the new kernel, and if possible how to revert back to my current version?

Thanks!

[bigoperm (bigoperm)]

When I switched from a PS/2 mouse to a USB one, my troubles decreased dramatically. At times, the pointer is still a little shaky (i.e. the mouse is physically stable, but its screen representation is unstable), but this shaky'ness is contained within a few pixels, rather than the entire screen (as was the case with the PS/2 mouse). Also, the USB mouse does not randomly click things either.

I'm running 2.6.24-16-generic

[Leann Ogasawara (leannogasawara)]

Hi Nicholas,

I'd suggest testing via a LiveCD since Alpha5 was released last week - http://www.ubuntu.com/testing/intrepid/alpha5 . Definitely let us know your results. Thanks.

[Matt LaPaglia (mlapaglia)]

Still having the same issue with intrepid running the latest updates.

[Steve Langasek (vorlon)]

marking invalid for linux-source-2.6.20, which is not in intrepid and beyond.

[Wilken Haase (hibbelharry)]

My Synaptics Touchpad and Trackstick on my HP NC6400 RH484EA Notebook suffer the same issue, Issue was already present in 8.04 ans is still present in 8.10 with latest updates. Adding i8042.nomux=1 to kernel parameters gave me no cure. rmmod psmouse and modprobing again does not always lead to success.
This really often happens just some minutes after boot and makes my inputdevices unusable.
USB Mice connected to my machine never gave me trouble. I also investigated when Touchpad dies cat /dev/input/mice gives me no more output.

Never seen the Problem on WinXP which is installed on my machine, too.

[thom (tsk)]

I had a similar problem when using an old KVM switch between mouse and computer.
my solution was:

sudo sh -c 'echo options psmouse proto=imps > /etc/modprobe.d/kvm-fix'
sudo modprobe -r psmouse
sudo modprobe psmouse

if it doesn't work for you, just do:

sudo rm /etc/modprobe.d/kvm-fix
sudo modprobe -r psmouse
sudo modprobe psmouse

and everything will be as it was.
note that the name "kvm-fix" is just an arbitrary name, could be any non-used name actually.
hope this helps.

[Thomas (tjustleft)]

I am running hardy 8.04.2 2.6.24-23-generic. For a week or more my optical wheel mouse is going crazy too. It will stop responding or just fly around and right click on it's own. I tried another one but it didn't help.

Syslog shows errors:

The same for messages log.

This is a fairly fresh install of Ubuntu. I did reinstall because of another problem where mouse and keyboard will stop responding when using firefox or opera. Freeze is so bad That I have to unplug the computer. Reinstall did not help.

[Morgan Olausson (ol-morgan)]

Hi, I just wanted to say that the problem I had with my mouse in this bug is solved.
The problems disappeared when I changed the mouse-cable.

[Thomas (tjustleft)]

I posted that I was having these mouse problems. Also that I was having a problem where mouse and keyboard will stop responding when using firefox or opera. Freeze is so bad That I have to unplug the computer. Reinstall did not help.

I thought these were unrelated, at least in my case. It turns out they may be related. I tried a third mouse. One with a, gasp, ball. While response feels clunky compared to what I was used to with an optical mouse the freezes and erratic mouse pointer have gone away. This includes no more mouse errors in logs.

Is it possible that Ubuntu is having problems with optical mice? If any of you have a ball type mouse give it a try. Please post if this does or doesn't stop erratic mouse and errors.

[Timo Salokas (timo-salokas)]

Hi Thomas,

I also noticed the same thing. As I got tired of the optical mouse's erratic actions I fired up the ol' Cordless MouseMan Wheel. It works perfectly - for a ball'd mouse.

But this is not the whole story. I'm a dual booter... yes, it's the games, and noticed that the optical mouse would shut itself off from time to time in Windows also! With an exception that Windows didn't recover as good as Kubuntu did. I had to disconnect the cable and put it back in, with a prey it worked for a while but not always. I tried searching the cable for a magic spot with some serious twisting sessions but ended up with frustration. It was the cord, I knew it, but I had nothing to prove it as to where the faulty spot was.

In conclusion, I'm now using ball mouse but will buy an optical one in the near future. I'm however confident that my problem was inside the mouse's cable, although I could not replicate the incident in a more sophisticated manner.

I've added a patch to the relevant kernel bug (http://bugzilla.kernel.org/show_bug.cgi?id=6105) that mostly fixes this. Some assistance would be appreciated.

[pinzia (pinzia)]

any news on this?

[utkatubuntu (just-utkarsh)]

i am on karmic 2.6.31-17-generic latest kernel version and tried following things
1. adding i8042.nomux=1 as kernel boot options
2. acpi_osi=Linux as kernal boot options
3.sudo rmmod psmouse && sudo modprobe psmouse
4.installing xfree86-driver-synaptics instead of xserver-xorg-input-synaptics
  after seeing duplicates i think this bug is not usb mouse or touchpad specific
5.as a desperate measure added following to /etc/modprobe.d/options.conf
   "options psmouse resetafter=10" but this even worsens the situation

this problem pops up randomly, mostly followed by ipw2200 firmware error.
interestingly it occurs mostly at office wifi network not at all home network.

[Bal (bal)]

 I recently bought 2000 pcs mice from manufacturer in China for sales in Nepal. Have been using Linux for more than 10 years, never though PS/2 mouse wouldn't work on latest kernels. My display box says "Tested on Debian/Ubuntu". Shocked to say that it does not work in Debian Squeeze/Sid. Kernels tested, 2.6.32, 2.6.33 etc. It works OK on FC4 with custom built kernel 2.6.20 and WinXP flowlessly. Other cheap ps2 mice work OK in this system. Tried everything acpi, demux, etc. Issue is exactly as stated in this bug. Has following hardware in my system.

Hi Bal

Please try to recompile the psmouse kernel module with the patch on the kernel bug for this, the link to it is http://bugzilla.kernel.org/attachment.cgi?id=25282

Let me know if it works.

Thank you
Damjan

[Bal (bal)]

Hi Damjan,

Thank you for the patch but it did not work. Applied the patch, one hunk did not patch properly, manually added the line to pamouse-bace.c (psmouse->badchecksum = 0;) for that particular hunk. The modules compiled OK, but did not load for some reason, I must have done something wrong when only compiling psmouse.ko module. So I downloaded the 2.6.33 again, patched the tree with latest patches, 2010-03-03. Then patched with above psmouse patch. And compiled the whole thing again.

Everything went OK. New Kernel is working perfectly, except for my PS2 Mouse. dmesg shows

[ 0.834356] mice: PS/2 mouse device common for all mice
[ 129.761657] psmouse.c: Wheel Mouse at isa0060/serio1/input0 lost synchronization, throwing 3 bytes away.
[ 130.265621] psmouse.c: resync failed, issuing reconnect request

This is a cheap mouse, but it works in other systems. Other PS2 work in my system too, Too confused!!

Sincerely

Bal

[Damjan Jovanovic (damjan-jov)]

Sorry Bal, that patch only addressed bad parity, your problem is timeouts instead.

Please try this new patch which addresses both.

[Bal (bal)]

Damjan,

Sorry to report that the new patch did not solve the problem. But seems like different input device was created this time.

Mouse does exactly the same thing. Here is the picture of my desktop, please take a look at the continuous creation of untitled folders on right side of my desktop until I plug out the mouse.

http://attaritech.net/errors/crazy_mouse.png

Thank you for taking time to solve this!

Bal

[Damjan Jovanovic (damjan-jov)]

Bal

Please try the following patch:
http://bugzilla.kernel.org/attachment.cgi?id=23750

If that doesn't work, try commenting out that entire "if" block marked with leading +'s in http://bugzilla.kernel.org/show_bug.cgi?id=6105#c37

If that still doesn't work, it may be a problem with your i8042 hardware. Can you reproduce this on a different motherboard? Go back to the unpatched psmouse driver, boot your kernel with the i8042.debug parameter, and attach the dmesg.

[Bal (bal)]

Damjan,

None of the above patches worked. All produced same condition. Here is the debug info with "i8042.debug" enabled with unpatched Debian kernel, but without the problem mouse attached. If you need that please let me know.

I haven't got another same motherboard. This mouse works on XP and FC4. I will try with Lenny stable sometime later today (I have a hard disk with Lenny installed and an extra Intel mother board, but that one is in disassembled condition.

What is surprising is : other PS2 mice work in this system too!!

Thank you!

[Damjan Jovanovic (damjan-jov)]

Bal,

The i8042.debug needs to be done with the mouse that breaks, and needs to include the time period during which the mouse broke.

When the mouse breaks, does it eventually settle if you leave it alone for a few seconds, or does it stay broken until you unplug it? My patches could affect this.

I'll send a patch that ignores the interrupt data if there is a timeout. I have no idea what it will do but let's see. Please try it.

[Bal (bal)]

Damjan,
I will try this latest patch in a moment. To answer the question: when I turn on computer with the problem mouse attached, it starts going crazy the first time I move and stays that way forever, until I unplug the cable.

It behaves same way with or without patched kernels.

Here is the dmesg with the problem mouse attatched. also a small part of "kern.log" attached.

[Bal (bal)]

dmesg log with the problem mouse attached.

[Bal (bal)]

This dmesg is at the begining after the boot process is complete. The above one is was after I plugged back after the first unplug.

[Bal (bal)]

Dear Damjan,

skip the PS/2 interrupt data on timeouts did not do anything to solve this problem. how do we proceed now?

Thank you!

[Damjan Jovanovic (damjan-jov)]

Bal

I am pretty sure that your problem is elsewhere, maybe in the i8042 driver. Do other computers exhibit the same problem with that mouse?

There's a final patch I can try to send you, which will freeze the mouse for a few seconds and reset it completely, but that's really a last resort.

[Bal (bal)]

Dear Damjan,

Yes, you are right, I don't think it's psmouse driver. It all points to some kind of hardware mismatch between my mouse and this particular computer. I would give up for "bad motherboard" or something like that if ohter ps2 mice did not work here.

This mouse works perfectly in another motherboard (Intel G30) in Lenny latest kernel 2.6.26 . In that computer I installed latest kernel this morning with the kernel patches applied (but not psmouse patches in this page). The mouse works OK with this too, 2.6.34-rc1-next-20100310+.

Then in the nvidia board (my problem motherboard) I did the same thing again, recompiled the kernel 2.6.34-rc1-next-20100310+ and it still does not work. same thing.

Some issues "impossible to figure out"

[Bal (bal)]

Hi Damjan,

I figured out this mouse did not work with some other boards too. In some boards no cursor at all, in others like described above, it went crazy. I found that this was no software issue, it did not matter what OS you used, it only mattered what motherboards you used.

When I had thousands of one particular type of Intel G31 chipset boards in my stock for which this mouse did not work, I had to find exactly what was it. It was the controller IC that is NOT COMPATIBLE (what's the reason?) with some boards, both cheap and expensive.

The problem controller IC was: MX84511FP. I replaced this IC with MX84521FP (without touching anything else), the mouse works like the best mouse in the world in all boards that I can test.

This bug seems to be fixed in Lucid.

[Damjan Jovanovic (damjan-jov)]

No, this bug is definitely not fixed in Lucid.

[Damjan Jovanovic (damjan-jov)]

This bug is now fixed in the latest Linux kernel git. Please backport to Lucid and earlier?

    Input: psmouse - ignore parity error for basic protocols

    Observing behavior of the other OS it appears that parity errors reported
    by the keyboard controller are being ignored and the data is processed
    as usual. Let's do the same for standard PS/2 protocols (bare, Intellimouse
    and Intellimouse Explorer) to provide better compatibility. Thsi should fix
    teh following bug:

    Thanks for Damjan Jovanovic for locating the source of issue and ideas
    for the patch.

I haven't had this bug on maverick yet.
Fixed for me.
Thank's

I'm having this issue on Maverick. It appears to be related to my recent switch between Broadcom STA wireless proprietary module (wl) to the more open b43.

[Selmi (selmi)]

still happens on maverick. i noticed it happens much more often if cpu is busy and there is also big network traffic. for example when i have rhytmbox playing in background, i am running eclipse, android emulator and i am also downloading something on background that it happens every few minutes

i didn't tried solution "# defoptions=quiet splash acpi_osi=Linux in /boot/grub/menu.lst and then run update-grub" because in grub2 there is no such file and i am not sure where to write it so it won't be overwritten

[papukaija (papukaija)]

Ubuntu won't get the fix until this bug is fixed by upstream (the upstream bug is linked to this bug - see the affects Linux entry at the top of this page).

[Luis Mondesi (lemsx1)]

I get this same behavior on an OQO (netbook-like device) whenever I hibernate the system.

[Tony B - San Francisco (tonyb)]

I think in grub 2 it is in /etc/default/grub

The following workaround worked for me:

sudo apt-get install acpi-support swsusp

Then edit /etc/default/acpi-support

MODULES="ppp_async ath5k psmouse"
MODULES_WHITELIST=""

I have the problem with my computer (10.10), laptop's(10.04 and 9.10) and now with my new installed server (10.04):

Removing the patch tag since the patch is forwarded upstream. Btw, the upstream fix went probably to Natty. Please confirm.
