Interesting. My setup is an Abit BP6 with a pair of 466mhz Celerons, Symbios UW scsi, Advansys narrow scsi, and a Hauppauge WinTV 401. (And a bunch of other junk, but that's the major stuff) I have no idea if USB works for me, because I haven't taken the 2.4-pre plunge, and the usb patch and reiserfs patch don't get along. So I patch with reiserfs and hold off on buying any usb peripherals for that system. > It is possibly just a coincidence, but it seems that scsi recovers > when the bttv stuff is loaded.

This is going to sound basic but make sure that the Adaptec scsi isn't shareing an IRQ with anything. AIC 78xx pci host adapters do not play well with others. They've given me so much trouble in SMP systems that I've basically sworn them off. They're not so all-fired wonderful as folks make them out to be. Barring that, you might try digging up the aic7xxx docs. I seem to recall there being a hack you should make to the source when compiling for smp. i - Eric
