Public bug reported:
On this new machine, I'm getting regular arbitrary crashes usually
within a few hours of boot. Syslog from what I believe is an example is
below.
Most commonly, it crashes in a firefox tab running a flash game (ITRTG
from kongregate.com); the affected Web Content process then sits in a D
state and cannot be killed (even by sudo kill -9, though that does
change it to zombie state), while top continues to show it using 100% of
a CPU. At this point, strace cannot attach to it and 'ps -eaf' will
hang, as will exercises such as trying to cat /proc/$PID/cmdline. A hard
reboot is the only thing that clears it: 'shutdown -r' or '-h' do not
succeed.
I have also had the whole system freeze, including at the X login
screen; I have not yet found further examples of syslog reports from
such cases.
Let me know if there's other information I can usefully provide.
