The vector is the most important part of this, not the pc. According to
Jay's posting of 2 weeks ago, which should go into the FAQ:

Machine checks are of four (4) types, as in the following table:

Code      Reason                  Example or Common Cause
====      ======                  =======================

620	System Correctable        correctable errors in the memory subsystem,
				  eg single bit ECC errors, detected async to
				  processor execution

630	Processor Correctable     correctable cache and TLB errors, detected
				  internally by the processor

660	System Uncorrectable      unrecoverable memory errors

670	Processor Uncorrectable   unrecoverable cache or TLB errors, or
                                  read of a non-existent I/O space location

This means that you're getting a double-bit error in your RAM. Jay implies
that the errors are reported asynchronously, so the PC doesn't mean
anything...
