I'm having something like this problem under 2.3.51 and had it using
2.3.99-pre6 as well with the ide-to-scsi emulation.

Curiously enough, I _didn't_ have it at home, only at work; home is a
K6-200 of no particular pedigree, work is a Dell OptiPlex GX110. The
thing which occurs to me is that something is going flakely with the
ATA66 bus in the Dell, but I have no clue what to check.

The most recent actual error message was:

scsi0 channel 0 : resetting for second half of retries.
SCSI bus is being reset for host 0 channel 0.
