Although I don't have any bt's or problem reports, I have had several
crashes on my SMP machine as well. The MPS setting in the bios was at 1.1,
put it to 1.4 and haven't had any problems since. The box wouldn't report
CPU states in top, except when we took the box to BSD/OS.
Box is a Dual Xeon 450
Thanks,

Subject: Panics on my SMP system
Hi there,
I recently had a crash on my SMP system. Actually, I have had a
number of crashes over the past six months, but have just recently had
time to configure the system to get the crash dumps. Like a good
citizen, I filed a problem report (kern/12127). I have now gotten
another crash. I have attached the backtrace from the crash dump. If
you refer to kern/12127, you will get all of the gory details about my
setup.I would like to know two things. Should I file a separate
problem report for this crash? Second, is there somewhere that I
should upload the vmcores and the kernel.debug for the relevant
developer to examine?
Thanks,
-Reggie
