The strange part about this is that I only notice these input output
errors while reading a large XFS dumpfile off of the tape. Reading the
TARed dumpfiles always seems to work fine, even when they are on the
same tape!

I'm hoping to boot with vanilla 2.6.16.18 later tonight to see if I
still have that OOPS I reported earlier also.
