Hey I've been having this problem for awhile on my laptop(IBM Thinkpad

when ever I resume my laptop from suspend(from hard drive or RAM) my
dmesg is filled with this and I am unable to do anything that requires
access to the hard drive.

ide: failed opcode was: unknown
hda: task_out_intr: status=0x51 { DriveReady SeekComplete Error }
hda: task_out_intr: error=0x10 { SectorIdNotFound }, LBAsect=74853287,
sector=74853287

Ah... it was the IDE driver, sorry. You can try using Alan Cox's libata pata drivers patch which is included in recent -mm trees. With the patch, libata ata_piix driver can drive the controller instead of ide and it has better error handling.

Be warned that the drive will come up as /dev/sda instead of /dev/hda and it currently doesn't disable host protected area unlike IDE, so your disk can be messed up.
