This may sound strange but there have been reports of problems using
SCSI disk drives. IIRC it had something to do with the Adaptec (29160)
controllers. A really good article on SCSI vs IDE is at
http://www.prorec.com/prorec/articles.nsf/articles/1A37C1C69674D6D786256950005D2C39
Some of that article may come as a shock to hard-core SCSI fans ;-) I'm
running - 2.4.22 lowlat/preempt, uniprocessor AthlonXP 1700+, 512MB RAM,
60GB ATA 100 5400rpm Maxtor IDE disk drive (data drive only), AZZA KT3AV
KT133A Socket A motherboard, ST Audio (Hoontech) C-Port DSP2000 on IRQ
10 (not shared, IRQ 9 is unused), reiserfs. I hardly ever get any xruns
on this system so I'm pretty amazed that you're getting them. What does
your interrupt setup look like? I don't remember if we'd already
covered the interrupts before. Do lspci -vvv and make sure that you're
using IRQ 9 or 10 (or possibly 11) and it's not shared.
