Looping with:

pciide0:0:0: lost interrupt
       type: ata tc_bcount: 16384 tc_skip: 0

This happens when I try to use UDMA with the EIO-1680 133 or an Abit
Hotrod (HPT366).

I used to run this machine (AS 600) with four internal Barracudas,
three SCSI-buses (ISP + AHA-2940) and three network cards. Now it has
a 9GB IBM SCSI + 60GB Maxtor and relevant controllers. I don't think
it's the PSU.

Is there something I could do to help to debug this ?
