How far back does yours degrade? I lose not just all UDMA but all
DMA too.

Huh.

Does it also make your machine hang for several seconds on any
sustained I/O? (My mouse cursor freezes on-screen in X, audio
playback skips... I haven't flooding it with network traffic of
any sort, but I bet it even drops UDP and ICMP packets and has a
gloriously high service time on TCP packets.)

Is this reasonable to expect when I've got an IDE drive that's not
doing DMA at all? (I've never had one in that state before.)
