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 - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
