[Bug 129260] Re: opteron amd64 data corruption

[Joseph Fisk]

OK, I compiled 2.6.22 from kernel.org and the error still appears.  I
ran:

while (true) ; do md5sum bigfile.sql ; done

bigfile.sql is around 16GB, and I ran that loop for about an hour, and
here's the results:

cb5714b4050178096ee5d7ebade86364  bigfile.sql

889c5e708c1c884ea4efd11bdd1ff2c6  bigfile.sql

Any suggestions on how to determine whether this is actually a bug and
not faulty hardware?  This machine ran memtest for almost a week with no
errors!
