If you can make it do it again then I need to know the stuff that is
displayed beyond the end_request report - the actual ATA error codes for
one.

It may not be the drives but you've provided almost no info so its hard
to tell at this point. The actual error data printed will give a much
better idea of what occurred - drive or otherwise.
