System freeze in Ubuntu and Fedora

[Diciannove]

In stress conditions i get system freeze in Ubuntu 10.10 and Fedora 14.
Now I have Ubuntu 10.10 with kernel 2.6.35-27 and testing Firefox 3.6.15 with "Grab and Drag" 2.7.6 Add-on on LXDE Desktop Environment.
No usefull messages.

[Diciannove (tech-diciannove)]

I try with new kernel released (2.6.35-28) and the freeze still happen.
Nothing in messages or syslog :(

[Nordheimer Michael (nordheimerm)]

Same with noapic, nolapic, acpi=off boot parameters and latest kernel 2.6.38.

[Nordheimer Michael (nordheimerm)]

i can add:
checked nwfermi-5.1 on kubuntu-10.10 amd64 freezes occurred more frequently

[Diciannove (tech-diciannove)]

djp,
can you help me to debug and give you some useful messages?
Thanks

I had X Freeze two times, but i dont know its caused by NWFermi.

My freezes looks: No mouse work, keyboard too, the screen was not refreshing - loging in by SSH and killing X with SIGKILL helped, restarted X and all worked fine.

[Serge Lages (serge-lages)]

I also experienced these freezes, but I modified 70-nw-fermi.conf by setting UseTouchHelp to 0 and setting big values to RightClickTimeout and DoubleClickTimeout (like 1000000000).

I didn't had enough time to really test these changes but my first test was encouraging. Can you test it ?

I've tested this settings - everything is perfect (2nd day of testings) except of the right click option which is disabled... Freezes are gone, for now at least...

[Olaf Jansen-Olliges (olaf-orb-net)]

Hi - i had theese freezes too with 0.50 and 0.51 the above (big values for RightClickTimeout and DoubleClickTimeout & UseTouchHelp = 0 ) seems to avoid the problem.

atm i'm running gentoo with kernel 2.6.37-rc1 since 2 days without any trouble. Is there Anything i should test or enable to debug this issue?
Freezes looked similar to WebNuLL: machine reacheable via ssh but no mouse/ no keyboard / no screen refresh and unfortunately nothing in any log

I'd really like to get the right mouse button back...

Olaf

BTW thx a lot for this driver :-)

[djp (djpnewton)]

Thank you for the feedback this should be fixed in the next release.

[Olaf Jansen-Olliges (olaf-orb-net)]

Hi,

i've tested 0.52 without the RightClickTimeout/DoubleClickTimeOut & UseTouchHelp=0 set and the freezes are still there. Is there anything i can do to help debugging this issue?

Best
  Olaf

[djp (djpnewton)]

This issue may be fixed by the new 0.6 release

[Olaf Jansen-Olliges (olaf-orb-net)]

Hi Daniel,

i gave it a try and got a freeze after a few seconds of usage ...

with this as the last lines in Xorg.0.log:

then i re-fetched the source for "nextwindow_drv.so" and recompiled it.

with this module i am running my machine now. WITHOUT freezes up to now. I hope this will stay stable... I'll report back after testing a little bit.

Many many thanks again...

Hi again,

machine is frozen again :-( - any ideas/suggestions

Bye

[djp (djpnewton)]

Perhaps we can start by making sure if the freeze is caused by
nextwindow_drv.so.

When the desktop freezes is the whole system frozen (ie can you still ssh in
and kill X)?

If you disable the X driver (say remove
/usr/share/X11/xorg.conf.d/70-nw-fermi.conf and restart X) do you still get
the freeze?

Hi,

the machine is reachable via ssh. But it is not possible to kill X. I tried this several times the effect is somehow strange. When theese freezes occur I still can do things on the machine but if i try to shutdown the machine the whole system freezes. Then only the powerbutton helps. (SysRq: Sync or reBoot has no effect either) This "deep-freeze" can be forced by killing X prozesses ...

I will try disabling the nextwindow_drv this afternoon when i'm back home... - i'll switch from kde to a simple window manager (twm) to get rid of as many side effects as possible.

THX for the feedback
   Olaf

Hi again,

without the nextwindow_drv no freezes the whole afternoon. Stressed the machine with several glxgears + mplayer running.

Hello,

I'm experiencing Freeze also on my computer !

I have a Asus eeeTop ET2010 on Ubuntu 11.04 x64 with default ubuntu driver in 1600x900 resolution.

I tried nw-fermi 0.6 and 0.6.1 with xf86-input-nextwindow for natty and oneiric. (each with each > 4 tries) and always the same result :
The computer boot perfect, the touchscreen works perfect and is calibrated.
I can use the computer for hours without freeze if I don't touch the screen but when I start using the touchscreen, it freezes completely after 10 to 30 seconds, it always freezes when I'm touching it.
If I uninstall the nwfermi, the computer never freezes when touching.

The freeze is complete (screen not refreshing, no keyboard, no mouse) I have to hard shutdown the computer !

I thought at one point that it could be related to the fglrx ATI driver so I removed it but problem still occurs with the default driver (which works better than the proprietary driver by the way !)

hope I gave enough details, any suggestion ?

thank you !

[Nordheimer Michael (nordheimerm)]

For now there is only one workaround:

comment 8: https://bugs.launchpad.net/nwfermi/+bug/737429/comments/8
UseTouchHelp to 0 and setting big values to >RightClickTimeout and DoubleClickTimeout (like 1000000000).

[Nordheimer Michael (nordheimerm)]

it's been 4 months since last post
Looks like project is dead?..

will this bug get fixed?
