:If I boot a kernel w/o the second processor support, it seems to work just
:fine.
:
:My kernel is about 4 days old, from the RELENG_3 branch.

:News via CNFS generates the problem relatively trivially (within 24-36
:hours). Running uniprocessor on the same hardware has not hung yet I
:believe.
:
:Anyway, I know Matt's been a busy little beaver over in -current, I was
:just curious if there were any obvious fixes for -stable...
:
:Thanks.
If you have the kernel configured for DDB you should be able to
break into it with ctl-alt-esc and do two things. First, a 'trace'
( just in case the current process is in a tight supervisor loop ),
then a 'ps' to see what various processes are blocked on. That might
give us enough info to narrow the problem down a bit.
