Symptoms are identical to mine as far as I can tell.
I did see fatal trap flash in one case, but couldn't read the crash info.
It doesn't always just hang, once I got fatal trap and a reboot, other
times I got a hard reboot without fatal trap printout.
Unfortunately I wasn't able to catch anything other than "fatal trap..."
before the machine cycled.
