hard drive problems

[Zane C. B.]

hdb: lost interrupt
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hda: drive not ready for command
hda: irq timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
ide0: reset: success

Any ideas what is happening or suggestions for testing for what is
happening?

smartctl -H /dev/hda and smartctl -l error /dev/hda show the drive as
being good.
