Many (most? all?) KT133A-based motherboards have a known issue with
the PCI bus that often results in an IDE transfer problem. However,
this was fixed (IIRC) in FreeBSD around the 4.5/4.6 timeframe (maybe
earlier). [ Hmmm. You're probably seeing another problem with 4.7. ]

I don't know how FreeBSD handles it. Under Windows, a dialog box
pops up when an overcurrent situation occurs, and the box contains a
button that'll reset and re-enable the bus.

Motherboards using the VIA KT133A chipset generally do not have a
good reputation.
