Am on

  • Ubuntu 10.04.2 LTS
  • Linux skiran 2.6.32-32-generic-pae #62-Ubuntu SMP Wed Apr 20 22:10:33 UTC 2011 i686 GNU/Linux

My machine froze for the 5th time in 2 days.

  • Had to reboot, and login to a failsafe session to collect and review logs.
  • ALT+F2 to run nm-applet, so that the network connectivity works
  • ALT+F2 to run gnome-do, to launch my applications (I prefer using gnome-do, to using menu options, or ALT+F2)

I noticed the following errors in the various /var/log/* files, at the time my machine last froze (around 14:32 on June 10)

In kern.log

Jun 10 14:32:17 skiran kernel: [    0.766164] PM: Resume from disk failed.

In syslog

Also in wcstatus.log noticed several errors, occurring at the time the machine froze. This is the IBM VPN client.

I have attached the kern.log, syslog, wcstatus.log, messages, dpkg.log (on pastebin.ubuntu.com. Contains messages generated on 10 June only) - thanks for the tip Jamess

Updates: 12 June I logged into gnome session, and had enabled Apport. Two minutes after logging in, the system froze. Logged back into fail-safe, and noticed these two crash reports in /var/crash: _usr_bin_skype.1000.crash, _usr_lib_gnome-do_Do.exe.1000.crash. Also /var/log/apport.log reported process 2222 caused signal 6. This process happens to be mono+gnome-do combination.

Am thinking this could be some problem related to mono - but then am not 100% sure. Referred to this link, and ran this command sudo apt-get purge libmono0 mono-common libgdiplus. Need to see if this makes a difference.

Please let me know if you find anything amiss, and can suggest a solution. I do not want to leave the failsafe session, till I come across some possible solutions.

You can use pastebin.ubuntu.com to paste logs and provide a link here. –  Jamess Jun 10 '11 at 10:14
    
Is this a desktop edition or server edition of Ubuntu ? –  Jamess Jun 10 '11 at 10:16
    
@Jamess, am using the desktop edition –  Kiran Subbaraman Jun 10 '11 at 11:26
    
Would you please add /var/log/messages as well near to the time of freeze ? Probably from 14:20 to 14:32 (until you rebooted) –  Jamess Jun 10 '11 at 11:35
    
done. messages at pastebin.ubuntu.com/623336 –  Kiran Subbaraman Jun 10 '11 at 11:46

I noticed that my system freeze happened every time I had Firefox open - totally weird, I know. FF was at 4.x level. But then, I was desperate to get a resolution for the system freeze problem; couldn't possibly work in the gnome-safe mode forever. I noticed that my update-manager did not complete installation of a set of updates, and that it always stopped at the "ubufox" update. ubufox - Ubuntu Firefox specific configuration defaults and apt support

Went into synaptic, removed ubufox, and noticed that Firefox then updated itself to 5.0. Also, a whole load of other updates happened: http://pastebin.ubuntu.com/640006/.

So, as it stands now, my machine has been functioning ok, in the regular gnome-session. Still not sure what was causing the problem, because I didn't come across some conclusive evidence. Closing this thread, by marking this as the answer.

Maybe you should try without the thinkpad_acpi module.

any reason you suspect this module? And can you share the purpose of this module, so that I understand what I could potentially lose out on disabling it. –  Kiran Subbaraman Jun 10 '11 at 13:13
