And I've begun to make a separate page solely for ATA/SATA issues, which
is still *very* much under development.  The DMA and timeout issues you
see are listed on that page.

If the LBA changes, then chances are it's not your disks.  SMART stats
might help validate/refute that.  Otherwise, sorry that there's no
solution, but rest assured, you're not alone.
