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. Jan
