Mark,
Check line 519, this is where it is printing the error (I believe) and the patch does not print the ata_op here.
It is in the ata_to_sense_error() function.
I've already patched, as you can see, recompiled, etc..
# patch -p0 < /tmp/b patching file linux/drivers/scsi/libata-scsi.c Reversed (or previously applied) patch detected! Assume -R? [n] #
Jul 9 15:22:57 p34 kernel: [4300704.724000] ata3: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ 0xb/00/00 Jul 9 15:22:57 p34 kernel: [4300704.724000] ata3: status=0x51 { DriveReady SeekComplete Error } Jul 9 15:22:57 p34 kernel: [4300704.724000] ata3: error=0x04 { DriveStatusError }
This part needs the ata_op:
519 translate_done: 520 printk(KERN_ERR "ata%u: translated ATA stat/err 0x%02x/%02x to " 521 "SCSI SK/ASC/ASCQ 0x%x/%02x/%02x\n", id, drv_stat, drv_err, 522 *sk, *asc, *ascq);
Justin.
