The two panics are pretty different.
Obviously I'm rather concerned with the issue as I fear
perhaps a processor may be at fault. Googling the first panic has
lead me
to wonder if it is tied to Parallels and the second is fairly
nebulous to me
at the moment. Please advise as to what you may see is going on
here:
Sat Nov 22 13:22:49 2008
panic(cpu 7 caller 0x00193077): "pmap_flush_tlbs() timeout: " "cpu(s)
failing to respond to interrupts, pmap=0x536500
cpus_to_respond=0x4"@/SourceCache/xnu/xnu-1228.7.58/osfmk/i386/
pmap.c:4580
CPU 3 held off interrupts too long (the cpus_to_respond is a mask)
This panic is a message from the core which noticed the problem, so
the backtrace is useless. 10.5.5 has some new code to report the
unresponsive processor, but not all cases can be covered. I would
tend to think this is a software issue, not a hardware issue.
Actually, this can be a hardware problem... but it usually implies a
firmwarey / software
misconfiguration of the hardware. I recently worked on a product that
had issues
responding to PCI-e read requests fast enough to prevent the issuing
CPU from
occasionally panic'ing this way.
