Hmm. It's either a NMI problem or a run away interrupt.
Unfortunately, it's seems to be specific to your H/W
so it would be hard for us to debug it.

You can boot into the kernel debugger and see for sure..
Add a -kd to the unix line in the grub menu.

module$ /platform/i86xpv/kernel/$ISADIR/unix /platform/i86xpv/kernel/$ISADIR/unix -kd

set a breakpoint on deadman

[0]> ::bp deadman

continue

[0]> :c


run through a bunch of breakpoints and then see
where we are.. Do that a few times.
[0]> ,10:c
[0]> $c

[0]> ,10:c
[0]> $c

[0]> ,10:c
[0]> $c

[0]> ,10:c
[0]> ::threadlist -v

If you get this far, see if you can put the threadlist
on a pastebin..


delete all breakpoints
[0]> :z
[0]> :c
