tough to write to the disk when the kernel is crashing. ditto the
network. that leaves VGAs and serial ports, which can be written to by
self contained emergency-crash routines...
IIRC, you said this was a Q9something quad core... thats a desktop
processor... does this server have ECC memory? (I ask, because few
desktop platforms do, while ECC is fairly standard on servers).
Without ECC, the system has no way of knowing it read in bad data from
the ram, and if the bad data happens to be code and that code happens to
be in the kernel, ka-RASH, without any detection or warning, it leaps
off into never-land, and you get a kernel fault, almost always resulting
in...
kernel panic
system halted
with no additional useful information available. with ECC memory,
single bit errors get corrected on the fly, and log an ECC error event,
while double bit errors result in a system halt with a message
indicating such.
