Subject: hda errors on iBook G4
Date: Fri, 22 Oct 2004 17:30:46 +0200 [thread overview]
Message-ID: <20041022173046.003bf2ea.colin@colino.net> (raw)
Hi,
I noticed hda status errors in my iBook G4's dmesg quite a long time
ago, but never looked any more... Today I just ran tests with hdparm and
this looks like really reproduceable:
Results are different whether I try it only or more, see below.
Any hint about where I should look at, and what kind of bug may cause
this error?
# hdparm -X69 /dev/hda
/dev/hda:
setting xfermode to 69 (UltraDMA mode5)
# dmesg -c
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hda: drive not ready for command
# hdparm -X68 /dev/hda
/dev/hda:
setting xfermode to 68 (UltraDMA mode4)
# dmesg -c
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }
ide: failed opcode was: unknown
hda: drive not ready for command
hda: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hda: DMA disabled
hda: drive not ready for command
ide0: reset: success
# hdparm -X68 /dev/hda
