[dynabook TX/66E] 12.04 freezes many times daily

[Joe Carey]

Steps to reproduce: Boot up computer, wait a few minutes, and it freezes. Fresh install of 12.04 64 bit and 12.10 32 bit also freeze. I've used kernels 3.2, 3.5, 3.8, 3.9, 2.6 and 3.0, Fedora also freezes. Oddly, it DOES NOT FREEZE if I am doing something processor intensive, like ripping a DVD or converting video. So whenever I boot up my computer, I have to immediately start ripping. I have tried to ssh into my computer from my wife's, but it is impossible while frozen note, it IS possible when my computer is not frozen.
Memtest shows no errors after running it all night. fsck shows nothing. Happens in unity 2d and unity 3d, guessing it's not compiz.

Steps to resolve: Hold down the power button.

Also, if I don't log in to x and just go straight to console, I still get freezes. No proprietary drivers either. My computer is kept dust free, it is not overheating. I tried noapic, nomodeset, acpi=off, and acpi_apic_instance=2 did not fix it.

Hitting the function button will toggle the light off and on after the freeze, but only in the first few seconds.

[Joe Carey (joecarey)]

I had great hopes for 3.9 and my computer, but I experienced a freeze within ten minutes.

[nuttzo33 (slucas1979)]

can also confirm that 3.9 kernel still has this issue.

[Mercer Rivière (vincentuq)]

Similar issue here. I'm fairly sure I saw different errors, i.e. not only nvidia.

After the below example, it's dead. It always concerns IRQ's. I enclose some examples from a rich gallery I have in /var/log.

3.2.0-35-generic #55-Ubuntu SMP Wed Dec 5 17:45:18 UTC 2012 i686 i686 i386 GNU/Linux

Just for completeness. But from what I read it does not matter much.

[Joe Carey (joecarey)]

Similar issue, or the same issue? Are you able to SSH in to your machine when it freezes?

[Mercer Rivière (vincentuq)]

I'm unable to ssh to my machine because it's desktop computer and when I use it I do not have physical access to any other machine (I will be able to verify it next week, though).

But... This is the same issue: screen+keyboard freezes, yet e.g. skype works so if I'm connected and speak with someone, I still hear him, can speak, etc.... Just keyboard+screen is hung.

So this is a similar issue - but pretty much the same ;)

Also, please check your /var/log/kern.log*

As for me: I'm using kubuntu (Xorg), no compiz; nvidia proprietary drivers.

[Joe Carey (joecarey)]

I don't use skype with anyone, or I'd test that too. Interesting that it works for you.
I'm in the process of uploading my kernel log, but I'm in Indonesia on holiday at the moment and the connection is wonky.

[Sandeep Laxman (sandeep-laxman)]

I have been having the same issue since the past 3 months. I am using Ubuntu 12.04 64 bit on Core-i5 2410 acer timelinex 3830tg. It freezes about once day and the only solution is a hard reboot.

Updating the kernel has not helped either. I generally happens when chrome is running. However it has happened at times when no applications are running as well.

[Joe Carey (joecarey)]

It seem to me that my issue has only been for a few months too. I switched to Ubuntu (on my old pc) and then bought this computer last summer and went on bragging about how flawlessly Ubuntu is and that all my friends should switch (ha ha). It's only been since January or so that I've had this problem.

[Mercer Rivière (vincentuq)]

I'm experiencing it after an upgrade to the latest LTS (from previous LTS).

[Joe Carey (joecarey)]

Ok... a bit of weirdness which I do not have the expertise to interpret. I forgot and left a game running in the background all day and no freeze since I started it. Before that, this morning, I had had four freezes in a half hour. Since my bug has a heat of only 20 and no one is assigned, I'll try doing this daily :P Ha ha.

[Joe Carey (joecarey)]

My bios was not up to date, so I updated it, but still experienced a freeze.

[Scott Ringwelski (sgringwe)]

Same issue here. I've found that it happens often (60% of the time) when I open a new tab in chrome or chromium and start typing in the url bar. As I'm typing it will then freeze. All screen output except for mouse is frozen - I can still move my mouse.

Sometimes the screen will freeze and if I wait for 20 seconds or so (haven't actually timed) the screen will flash black and resume.

This issue used to happen maybe twice a week but as of the past few days it has happened at a rate of every 30-60 minutes or so of active use. Sometimes it freezes 20 seconds after start up and sometimes it can run for a few hours first.

I am going to try completely clearing out my browsing history - if I recall correctly chrome does not ever clear the history/trim it and it could potentially be causing the hang up.

I am running a dell latitude e5520.

[Mercer Rivière (vincentuq)]

Btw. I did not experience it on the previous LTS, which shipped with 2.6.x kernel. This feature arrived with kernel from the latest LTS.

Please search for kernel panics in kern.log.

This is almost certainly a kernel bug, not browser, not X (although this one segfaults from time to time as well - a separate problem).

[Scott Ringwelski (sgringwe)]

It turns out that I had another error going on at the same time with the same symptoms: https://bugs.launchpad.net/pantheon-dock/+bug/1157453. Doing that fix mentioned and clearing chrome's history resulted in no crashes over past 3 hours.

[Joe Carey (joecarey)]

Scott, if you get a freeze but are still able to move your mouse, consider filing another bug report, unless the above has finally solved your problem. When I get a freeze, everything is frozen, no mouse, no keyboard and nothing writes to the hard drive either it seems.

[Scott Ringwelski (sgringwe)]

Joe - solved my problem. I should have said that it is the same symptoms except for one the mouse froze and one it didn't. So one had the same symptoms as yours and the other had same symptoms except I could move my mouse.

[Joe Carey (joecarey)]

This freeze cost me 3 blank dvds today and who knows how much it will shorten the life of my hard drive. :(
I tried 13.04 today, still freezes. If it is hardware failure, which piece of hardware is it? Still at wit's end.

[Frank Schilder (f-schilder)]

I recently upgraded to Ubunto 12.04LTS and since then observe the same problem. Initially I followd the discussion in <https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/993187>, but it seems to have gone to a dead end.

I would like to share some observations that hopefully help someone else to get closer to the source of this issue. My suspicion is a kernel problem. I kept a terminal with 'tail -f /var/log/syslog' open to see if something unusual happens before the computer freezes. And yes, every time just before the computer freezes, this is what is written en masse to the syslog:

[jenna (giantpune)]

I'm also experiencing this bug. I'm using Kubuntu 12.04 on 4 different computers since that version was released. Computer 1 is a desktop with AMD processor and 8GB of ram, and it has never had this issue. Computer 2 and 3 are laptops with Intel core Duo processors and 2 and 4 GB of ram and have never had this issue. Computer 4 is a laptop with a core 5i and 16GB of ram and I get this issue several times a day. All 4 computers are used by the same person (me) to do the same tasks and have the same programs and settings.

Just as comment #36, I get this freeze very frequently while typing in the URL bar in google chrome.

[Joe Carey (joecarey)]

It probably happens while tying in the URL bar because you frequently type in the URL bar. Not the cause of the problem, just coincidence.

I installed Fedora yesterday and got a freeze within minutes with it too.

As a last resort, I might have to install XP.

I'm glad to see bug heat is rising on this, maybe it will get some attention and be fixed.

Either that or I have bad hardware and nothing can be done at all :(

[Joe Carey (joecarey)]

https://wiki.ubuntu.com/Core_2_Duo_Support

This maybe?

If so, the problem has been around for a long time.

[Frank Schilder (f-schilder)]

[Joe Carey (joecarey)]

Sadly (?) my kern.log doesn't show any such thing.

[Joe Carey (joecarey)]

For further insanity, after freezing 8 times or so this morning, I attempted to rip a DVD. Didn't freeze the whole time. About ten minutes after it was done, froze. So today, when I have wanted to use my computer for any length of time, I've been ripping the same DVD over and over again. Coincidence? I have no idea, but so far so good. Whatever gets me through the day.

[Frank Schilder (f-schilder)]

Hi Joe,

I think it is very well possible that this is not detected in the same way on every hardware. As far as I can see, the log messages I posted above contain at least some indication for a kernel developer where to look for. I think this is a very hard to locate bug and we should try to collect all possible evidence that might lead to its source.

[Joe Carey (joecarey)]

I agree wholeheartedly. If there is any more info I should provide, please let me know.

[Joe Carey (joecarey)]

Ok experts who love solving puzzles. When I go to work, I leave ushare up and running so my wife can stream videos for my son (he's 2). Lately, of course, it's been freezing and so we can't. As an experiment, since by odd chance it seemed to work, I've been setting Thoggen DVD ripper to rip a dvd (the same one over and over) while I'm gone. My wife has confirmed that shortly after the DVD finishes ripping my computer freezes. But never DURING the rip. What the heck does that mean for this bug and my computer???

[Joe Carey (joecarey)]

After five days, absolutely no freezes at all while my processor is busy ripping a DVD.

Usually freezes within ten minutes of finishing. Heeeeelp! I'm sure ripping DVDs is illegal in Japan, not to mention running the DVD drive all the time being probably not so great for its lifespan.

[Mark Breman (breman-mark)]

I (and many others) had the same problem on ubuntu 10 (there is a 200 page thread on ubuntuforums.org about it) and now i have the same problem again after upgrading to 12.04. I tried with kernel 3.2.0-39 and 3.2.0-40 with different versions of the nvidia drivers but the freezes remain.

On ubuntu 10 (Lucid) i "fixed" the problem by setting all window effects to off in gnome/compiz.

Now with 12.04 and running Unity i found a similar setting after installing the Myunity package. It is on the Desktop tab of myunity called "Windows animations" and it's ON by default.

I changed the setting to OFF yesterday and will report back if i experience another freeze...

[Joe Carey (joecarey)]

I'll give that a shot too, but it seems unlikely to help in my case. I have had freezes while not running x at all.

[Joe Carey (joecarey)]

@Mark Breman please report back if you do NOT experience another freeze too please!

[Mercer Rivière (vincentuq)]

I'm using X11 (KDE) and never used compiz.

[Mark Breman (breman-mark)]

I'm running without freezes now for a couple of days after setting "Windows animations" off in Myunity.

It's too early to call it a workaround yet but i'm hopefull it will solve my problems just like it did in Ubuntu 10.

@Joe Carey: if you experience freezes without running X it's more than likely that we experience the same symptoms for a different problem. I think it's very unlikely that this workaround (maybe) will help you.

[Joe Carey (joecarey)]

@Mark Breman

Indeed, we have a different problem.
My workaround is not ideal at all. I constantly rip DVDs.

[Joe Carey (joecarey)]

CPU power state problem?

[Maffiou (maffiou)]

Seen the problem on a DELL Latitude E6530 while trying to upload a file through Chrome
(running 12.04 with disc encryption. (Computer complained about disk at first restart, not sure if this is relevant))

[Denis Kuznetsov (denis-v)]

I have the same problem on 2 of 3 my servers. Hardware configuration is the same on them all:

Intel® Core™ i7-2600 Quadcore
incl. Hyper-Threading Technology
RAM32 GB DDR3 RAMHard disks2 x 3 TB SATA 6 Gb/s HDD
7200 rpm (Software-RAID 1)

Ubuntu 12.04, upgraded all the packages. Updated the kernel:
uname -r
3.9.0-030900-generic

As it runs on my servers, no X-server is used. It hangs and I cannot get to the servers through SSH.
One of the servers runs Mysql , another one only my Ruby On Rails application.
What logs do you need to diagnose and fix the bug?

[Rabit rabit (o2918474)]

After running 12.04 LTS for months I finally gave up. I'm back to windows now.

I have exactly the same problem. Totally *random* crashes. No mouse, No keyboard, No ssh. Nothing at all. But in my case after a while (about 15-30 seconds) it will reboots itself.

I have tried kernel 3.2.x all the way to 3.6.x. Now I'm using 3.5.0-25 which seems to a bit better, but still freezes. But sadly I have been back to windows for 3 months now.

Freezes happens randomly, but many times (not always) it happens after I plays some videos or mp3. Sometimes it happens while the computer is idling (just my firefox running).

I have a legacy system which proves stable under Windows. Asus MB, 2GB ram, Core2Duo, nVidia geforce 7600GT. I'm not running Unity. I use gnome classic.

[Mark Breman (breman-mark)]

Yesterday i had another freeze after more than two weeks without any freezes at all (after setting Windows animations off in Unity). I was watching a long youtube video using Chrome with the flash-plugin which has proven to be unstable and causing freezes in the past...

Maybe there are multiple causes for these freezes?

"I have a legacy system which proves stable under Windows. Asus MB, 2GB ram, Core2Duo, nVidia geforce 7600GT"
I'm also using Asus motherboard, Intel core2 quad cpu, nVidia 9600GT, 8GB RAM.

At the moment i'm running the latest LTS kernel: 3.2.0-41-generic-pae.

[Joe Carey (joecarey)]

There are definitely multiple bugs here at play. If you went two weeks without a freeze, please file another bug report. I cannot go 15 minutes without a freeze.

[Mercer Rivière (vincentuq)]

Please try disabling vdpau in the driver or it's use by any software?

[Joe Carey (joecarey)]

Sooooooo... after months of wrestling with this, a problem I thought I had ruled out is indeed the problem.

If I unplug my laptop and run it with just the battery, NO FREEZES. Of course the battery will only last so long. But the moment I plug the beast back in, it freezes. I swapped a/c adaptors, power bar and tried a different wall outlet. The jack on the laptop itself doesn't seem to be loose, so I can only conclude that it's something on the motherboard and I think it'd be cheaper to scrap it than to have it fixed.

So, dude, I'm gettin' a Dell. about 150 bucks in Japan, new, for their bottom-of-the-line model. Sigh.

For anyone else suffering random freezes, good luck. I'm going to retire from this thread.

[Joe Carey (joecarey)]

My problem might be NEC/TOKIN 0E128 Proadlizer Capacitors OE128.

A google search

sorry for the long link, shows more than a few with this problem with their crappy Toshiba laptops. I have never soldered anything before, and though I would like to learn, I can only imagine that with my current skill level I'll burn my house down trying to fix this.

[Joe Carey (joecarey)]

Here it is.

[penalvch (penalvch)]

Joe Carey, , as per http://dynabook.com/assistpc/download/modify/dynabook/tx/tx6xe/bios/index_j.htm an update is available for your BIOS (2.50). If you update to this, does it change anything?

If not, could you please provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

[Joe Carey (joecarey)]

Hey, thanks for checking. Yes, since I originally posted this, I have updated the BIOS to 2.50 and there is no change.

The output is:

2.50
12/08/2008

[penalvch (penalvch)]

Joe Carey, thank you for updating your BIOS. Could you please test the latest upstream kernel available (v3.10-rc7) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.10-rc7

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

[Joe Carey (joecarey)]

Thanks, I've updated the tags.

I really hope this is a bug that can be fixed but I now have a very strong suspicion that this is a hardware issue. Hopefully I'll be proven wrong :D

[Daniel Arnitz (daniel-arnitz)]

I can confirm the bug with kernel 3.5.0-34-generic (on Kubuntu 12.04 LTS). I don't think it is a hardware issue.

I'm not sure if this helps, but high CPU loads prevent the system freezes.

I am using the Kubuntu machine to control lab equipment over Ethernet (SCPI, low cpu load, some network, a couple of GB memory) . I had regular freezes every 12 to 36 hours. Inserting some random computation (inverting a 16x16 matrix at least once a second) fixed the problem. Uptime is now 11 days and still counting.

[Joe Carey (joecarey)]

Same symptom, high load prevents freezes. Or at least used to for me. Lately my problem is worse.

[penalvch (penalvch)]

Joe Carey, when you said you tested kernel 2.6, was this mainline, or were you in a Lucid environment?

[Joe Carey (joecarey)]

I was using precise but with the 2.6 kernel. Not long, only until a freeze occurred.

[Joe Carey (joecarey)]

Lately, I have been having trouble booting at all. I found out that if I unplug the laptop and then boot, usually (ha, not always) it will boot. Then I have to promptly run a ripper to keep the machine going (and now this doesn't always work).

I noticed that when it does not boot, the hard drive LED goes off and stays off at and at that point, boot fails.

Just to see, while booting and not plugged in, I suddenly plugged it in , hard drive LED goes off.

[penalvch (penalvch)]

Joe Carey, for regression testing purposes, could you please test for this in a Lucid environment via http://releases.ubuntu.com/lucid/ ?

[Joe Carey (joecarey)]

Having a bit of a hard time getting through the installation without a freeze :(

[penalvch (penalvch)]

Joe Carey, any change with the latest mainline kernel via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc7-saucy/ ?

[rsoika (ralph-soika)]

I am also affected from this issue (see: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1137817)

With 3.11.0-031100rc7-generic my system becomes much more stable as with any of the kernel versions before (I am testing every new kernel version since February this year).

More stable to me means: before 3.11-rc7 I my system freezes 1-3 times in one day. Now I had the first freeze after 2 days.

[Launchpad Janitor (janitor)]

[Expired for linux (Ubuntu) because there has been no activity for 60 days.]
