ICH4-M ACPI Error

[Lee Trager <Lee@PicturesInMotion.net>]

Hey I've been having this problem for awhile on my laptop(IBM Thinkpad
T40) and have no been able to figure out how to fix it. It seems that
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

I checked the drive with the IBM hardware analysis tools as well as the
Hitachi Drive Fitness extended test and both say the drive is fine. What
is strange is that according to hdparm my drive only has 72037362
sectors while this error is on sector 74853287.

This error happens with and without wireless, DMA, and alsa. The kernel
option in ATA/ATAPI/MFM/RLL support named IDEDISK_MULTI_MODE does not
fix the error. I have also tested this with the mainline kernel, supend2
sources, gentoo sources, and the Knoppix boot disc and this error
happens on all of them. I talked to one of the suspend2 developers and
he said that the problem is with my IDE driver not properly waking the
drive up. Could someone please help me?

Here is some system information

Distribution: Gentoo 2006.0
Laptop: IBM Thinkpad T40
IDE Controller: Intel Corporation 82801DBM (ICH4-M) IDE Controller (rev 01)
Harddrive: Hitachi IC25N040ATCS05-0
Software Environment:
GLIBC: 2.4
GCC: 4.1.1
Kernel: Gentoo-sources-2.6.17-r5(although I tried with a number of other
sources as stated above)

Thanks,


Lee
