ICH5 ATA DMA timeouts

[Perry Hutchison]

Er, there's nothing to check, yet.  I'm trying to *avoid* trouble
by finding out in advance about any dodgy hardware support.

In several of the cited threads, it was pretty clear that the
hardware was not faulty, since the identical hardware had run
properly on 4.x but started generating DMA timeouts on 5.x; also
diagnostics were run (=> drives OK), cables replaced, etc.  In at
least one case the failure was reproduced on a different box than
where it had originally been observed.

It was suspected that there might have been some kind of interaction
between geom and the ATA code, e.g. a timing problem, since many of
the failures involved software mirroring (vinum or gmirror).
