Comment 1 Dave Jones 2012-02-27 20:49:43 UTC 
that trace in bug 794833 looks different.

Was this after a hibernate/suspend ?
Comment 2 Khaled Abdo 2012-02-27 21:02:31 UTC 
Nope, I never shutdown/Hibernate/suspend my machine .. it's always on .. 
I dont precisely remember all programs that were running, but for sure Azureus, Google Chrome, and maybe VLC ... 

Also note that I am running KDE (Plasma Desktop) not GNOME3.

this, and your other bug in 794833 are quite out of the ordinary.
Does this machine pass a memtest86 run ?
