I have noticed the same thing here in two situations:

1. IBM DTTA-351010 UDMA 2 10.1GB IDE drive on primary master,
   SONY CDU-55E PIO 0 2x IDE CDROM on secondary master.

2. Western Digital AC2420F PIO 3 420MB IDE drive on primary master,
   Seagate ST31276A PIO 4 1.2GB IDE drive on primary slave,
   assorted CD-ROMS on secondary channel.

System 1 is an Intel TX chipset, 2 is some SiS Aladdin thingamajig.
Removing the SONY from system 1, or even disabling the second IDE channel
fixes the problem.  In system 2 i *think* the problem disappeared if I
replaced the WD AC2420F with an IBM 540MB PIO 2 drive, but I am not
completely sure on that because the SONY CD was on secondary in that system
for a time, and that could have been what was causing it.

If anybody is interested I can give more detailed info or do some testing.
I know this problem is in both 2.2.5-PREREL and 3.2-STABLE from about a
week ago.
