Last modified: 2015-01-04 17:10:02 EST
Description of problem: The kernel oopses occasionally during normal usage. Not always noticable as a user, sometimes the computer feels frozen for a while.

Same here [tm]. The exact same oops happens to me - It happens when the xorg server starts up after a reboot.
This is no longer the case with my laptop. I did an upgrade to FC3T3 and now it works.
