Oh boy is that familiar! I just spent a week troubleshooting exactly
the same error on one of our servers. The bug report is here:
https://bugzilla.redhat.com/show_bug.cgi?id=379771
The answer (or at least workround) was to append:
libata.pata_dma=1
..to the kenerl boot line. The new ata lib seems to cause a lot of
problems for a lot of people.
Hope this helps
Simon.
