• 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

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.
