Kernel panic on power button

[Eitan Adler]

I just pressed the power button on my desktop computer - it seemed
like it was attempting to do an ACPI suspend instead of a power down
like I expected - but I'm not sure.

Either way:
When It got close to the end

I got

Kernel trap 12: page fault in kernel mode
followed by the fault address, instruction pointer, etc. I have the
information written it down if it would help.
At the end it said "unable to dump - device not configured"
uptime: 11d...

The current process was listed as 81250 (tmux) if that matter.

I then needed to perform a hard shutdown of the computer.

uname -a

What debugging data should I provide to help fix this issue?
