Most vendor are -ac based. The IDE changes in Linus tree match the
Andre code with my fixes for the Dell cable detect. The -ac tree contains
an additional trap for the seagate problem we are chasing but is otherwise
the same

The extra trap in the -ac tree may be useful as it should trigger on the
seagate problem. If you can pull a box out of service I have a test set from
an RH customer with this problem that replicates the UDMA problem remarkably
reliably and rapidly for them (but not on serverworks own tests so its
not a simple problem). It would be useful to know if the seagate problem is
replicable and shows up the same way on your boxen

Info on the precise seagate drives, and pci data on the machines would be
very useful too so I can compare it to the other case and also pass it on
to serverworks.
