The system with the failure has been running with only 1 GB (1 DIMM,
instead of 2 to make 2 GB).  Since then I've been copying pictures just
the same, with zero trouble since removing the memory.  The
suspected-bad dimm is going back to the vendor for testing.

I have 4 other systems, 2 almost identical to the one with trouble, and
2 very different, and none of them have shown any trouble.
