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.
