For another, perhaps unrelated datum, my Athlon64-X2 box has become wonderfully stable and seemingly fully functional ever since I took all of the PCI cards out of it. I wasn't trying to run SCSI disks (just on-board SATA), but I was trying to use PCI network adaptors, since there was no driver for the on-board NVidia MCP9 at the time. (I'm now using the experimental nfe driver, and it seems to work great.) I tried a bog-standard crappy RTL8139 and a good-as-gold Intel 21143, and they both displayed symptoms consistent with missing interrupts: failure to detect carrier, multiple up/downs from watchdog timeouts, etc. Now, my Gigabyte Nvidia4 board has a totally different motherboard chipset from the MSI K8D Master-F in question, but the similar behaviour just seemed interesting. There isn't any vm86-mode setup (bios calls?) involved in routing interrupts, is there? Any similarity in BIOS vendors between the two boards? (Maybe firmware bug?) Cheers, -- Andrew
