My PIII-733/PC133/i815E system with a Barracuda II UDMA/66 drive is getting
these occasionally:

Mar 28 00:38:42 kei /netbsd: pciide0:0:0: lost interrupt
Mar 28 00:38:42 kei /netbsd:    type: ata tc_bcount: 8192 tc_skip: 0
Mar 28 00:38:42 kei /netbsd: wd0e: device timeout reading fsbn 6491088 of 6491088-6491103 (wd0 bn 8588736; cn 8520 tn 9 sn 9), retrying
Mar 28 00:38:42 kei /netbsd: wd0: soft error (corrected)

This system used to be running FreeBSD; 4.1.x couldn't handle the errors
after a few days and locked the machine, 4.2 drops down to PIO mode at the
first sign of trouble, which works but is sloooow.

I've been running 1.5 for a few days now after trying 1.5S on it, and both
of those manage to keep using UDMA in spite of the occasional lost interrupt
sequence like the above. When it happens, the machine goes away for a few
seconds and I can hear the HD making a distinctly unusual noise.

But at least NetBSD recovers, which is better than I can say for FreeBSD.

Any ideas? Full dmesg below.
