Can you show the stack traceback from the kernel core?
We had a problem a while ago at Isilon that I can't tell if it's
related. In our case, the camisr() routine was called after panic(9)
started and before the halt of other processors. This did Bad
Things(TM) since the mtx_lock is a no-op after panicstr is set.
We solved it locally by wrapping camisr() in a local cambio_swi()
routine that only called camisr(NULL) when panicstr == NULL.
Thanks,

Hello.
I will do as soon as possible. The box is in production at the moment
and I've less time to put everything into debugging to provide more details.
Just in case: does the kernel automatically save the screen with the
dump information? If not, I have no other terminal facility to get a
dump via the classical way.

Oliver
