I solved this problem by adding 'pata_marvell' to /etc/initramfs-tools/modules and then rebuilding the initial boot image by typing 'sudo update-initramfs -u'. My guess is that pata_marvell wasn't being loaded early enough. Is this behaviour a bug/regression in the kernel, or just a quirk of my setup? -- Joe Hickey -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
