The "root cause" may be hard to determine, but the immediate cause was
helpfully decoded by the kernel. (Though I don't know whether all of the
model-specific fields were decoded.)
UNCOR = uncorrected error
PCC = processor context corrupted (can't safely continue to execute, thus the
OVER = error overflow (hmmm, multiple errors occurred)
DCACHE L2 DRD = data being read from L2 data cache
The miscellaneous register indicates that 0xbd8d4cc0 is a physical address.
So this looks like a processor failure. If it is repeatable, though, it may
indicate either failed hardware or some problem in configuring the processor
(though I'm not sure how that could lead to a cache error).
