Hello,
2.6.23.8 just crashed here, it had been up 8 days and suspended to
disk many times in those 8 days. The process that crashed it was
firefox-3.0b1. It crashed and could not be killed (please excuse me, I
failed to get ps auxf output).
All of the following information was after reboot, except, of course,
for the BUG.
