After recompiling the kernel to enable CONFIG_BLK_DEV_SIS5513=y for my mobo's SiS 735 chipset, I reversed the test. The Maxtor drive is working like a dream (hope it doesn't wake up). By itself. So the problem seems not to be the drives themselves, but how one (Fujitsu 20 GB, UDMA 66, master) plays with the other (Maxtor 60GB, UDMA 100). So does anybody know of any kernel boot parameter (something like hda|hdb=xxx) I can pass to grub to let these two live together in peace? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
