Same Problem here, the harddrive (2.5" Samsung HM121HC) running with
Kernel 2.6.18-194.32.1.el5 (x86_64) produces errors on high load.
With one step back kernel the errors are gone. Im already changed the
harddrive with a new one, same errors on the newest kernel.
dmesg output:
hdc: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hdc: drive not ready for command

There are no errors logged in smart, i already try'd with smartctl -t
long .... no errors. I also did a blocktest on this drive.
Next step is to change the cables, but i don't think this would be a
solution, i think it's a kernel IDE / DMA problem.
