IBM and Western Digital have been known to NOT follow the ATA spec
correctly.

On non-Intel/SiS chipsets (SiS being an Intel licensee), this is then an
issue since IBM/WD only test their products on Intel chipsets.  And even
then, they were usually designed for the older Intel PIIX southbridges
(i440-series), and can take issue with the newer Intel iCH2 southbridges
(i800-series).  I know, I've had IBM/WD timeouts on Intel i815 and i845
P3/P4 chipsets as well as ViA Pro/133 to KT266 chipsets.

I don't know about IBM, but Western Digital's response has been to state
"we don't support Linux."

Either set the drive into PIO ("/sbin/hdparm -d 0 -u 0 /dev/hda"), or
get another hard drive.
