I've two things in mind to try: (1) there is 1 newer official BIOS release and 2 beta BIOSes out for this motherboard. The recent official BIOS (0901) does mention Linux: "Fixed Red Hat Enterprise Linux 4 installation failed" So maybe a BIOS update will fix things. (2) I will try booting with the "noapic" kernel option to see what difference that makes. > Neither are good, the latter is probably a drive firmware problem and > the kernel will give up using NCQ with it if it keeps doing that, > which should be just fine. So I guess these drives should be added to the ata_blacklist_entry in libata-core.c with ATA_HORKAGE_NONCQ? Stirk, Lamont & Associates Ltd.
