Public bug reported: Not sure if I have gathered the information correctly. I run ubuntu 12.04LTS with xswat repository.
Periodically I get what I presume is a kernel panic while watching flash video. I video will freeze up but audio will continue for some seconds. Then I will get dumped out to a screen with some traces on it, audio will loop the last second or so. I am unable to switch to a vterm or do anything other than hold the power button and switch off the machine. The following messages in kern.log correlate with the time of todays crash.
