[Some email archaeology later] Back in March I was running 2.6.16 (with the opcode patch) and I sent an email with the following info: dmesg: ata1: translated op=0x28 cmd=0x25 ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ 0xb/00/00 ata1: status=0x51 { DriveReady SeekComplete Error } ata1: error=0x04 { DriveStatusError } Does that help with the diagnosis? Also see my emails: SMART on SATA reporting errors? http://marc.theaimsgroup.com/?l=linux-ide&m=113933732903205&w=2 I did reply but got no response so I assumed I was just so far off base that I was being ignored :) David David Greaves wrote: > Mark Lord wrote: > >> MMm.. probably "barrier" commands that the drive doesn't like. >> Pity those messages don't also dump the failed opcode. >> > For me: > smartctl -data -o on /dev/sda > produces this on 2.6.17-rc5 > > (I thought the opcode patch went into 2.6.17...) > > ata1: PIO error > ata1: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ 0xb/00/00 > ata1: status=0x51 { DriveReady SeekComplete Error } > ata1: error=0x04 { DriveStatusError } > ata1: PIO error > ata1: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ 0xb/00/00 > ata1: status=0x51 { DriveReady SeekComplete Error } > ata1: error=0x04 { DriveStatusError } > ata1: PIO error > ata1: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ 0xb/00/00 > ata1: status=0x51 { DriveReady SeekComplete Error } > ata1: error=0x04 { DriveStatusError } > ata1: PIO error > ata1: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ 0xb/00/00 > ata1: status=0x51 { DriveReady SeekComplete Error } > ata1: error=0x04 { DriveStatusError } > ata1: PIO error > ata1: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ 0xb/00/00 > ata1: status=0x51 { DriveReady SeekComplete Error } > ata1: error=0x04 { DriveStatusError } > ata1: PIO error > ata1: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ 0xb/00/00 > ata1: status=0x51 { DriveReady SeekComplete Error } > ata1: error=0x04 { DriveStatusError } > > David > > >>> Jun 20 03:14:20 p34 kernel: [4339456.678000] ata3: status=0x51 { >>> DriveReady SeekComplete Error } >>> Jun 20 03:14:20 p34 kernel: [4339456.678000] ata3: error=0x04 { >>> DriveStatusError } >>> Jun 20 03:20:27 p34 kernel: [4339823.900000] ata3: status=0x51 { >>> DriveReady SeekComplete Error } >>> Jun 20 03:20:27 p34 kernel: [4339823.900000] ata3: error=0x04 { >>> DriveStatusError } >>> Jun 20 03:36:44 p34 kernel: [4340801.772000] ata3: no sense >>> translation for status: 0x51 >>> Jun 20 03:36:44 p34 kernel: [4340801.772000] ata3: status=0x51 { >>> DriveReady SeekComplete Error } >>> Jun 20 03:41:04 p34 kernel: [4341061.844000] ata3: no sense >>> translation for status: 0x51 >>> Jun 20 03:41:04 p34 kernel: [4341061.844000] ata3: status=0x51 { >>> DriveReady SeekComplete Error } >>> Jun 20 03:46:27 p34 kernel: [4341384.974000] ata3: no sense >>> translation for status: 0x51 >>> Jun 20 03:46:27 p34 kernel: [4341384.974000] ata3: status=0x51 { >>> DriveReady SeekComplete Error } >>> > > - > : 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 > > -- - : 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
