Re: unknown mtx_assert at /usr/src/sys/x86/x86/io_apic.c:161

John:

Thanks, I actually didn¹t see the MCA errors on the screen as the system has
reloaded but noted them in the ddb.txt file last night.

The Motherboard, CPU, Memory and PS were replaced today.  I¹ll post back if
this has or not corrected the problem but I suspect you are on target in
that the hardware was defective.  This machine was remote and I found the
fan in the power supply not working, so I¹m suspecting that the CPU was or
other logic was damaged.

Thanks for your reply.
