SubjectRe: Corruption Stats (fwd)
This one is another SMP motherboard.

I wonder if there are any non-SMP reports at all?

Mmm.. That one (above) is puzzling. Are you sure?

WD has a non-announced bug with UDMA support on certain models,
which I just found out about from reading some "semi-secret"
material sent to me from a vendor of IDE-interface boards.

But the drives listed there are the AC35100 and AC36400.
Or maybe those are the only ones we know about..
I suppose we'll need to blacklist those models permanently.
