Bug#357283: linux-image-2.6.15-1-amd64-k8: kernel crash in ata_poll_qc_complete in libata
Package: kernel
Version: 2.6.15-8
Severity: important
Hi,
this system has an Asus A8V motherboard with an integrated 2 channels
SATA controller. It has 2 SATA disks (/dev/sda and /dev/sdb) that are
assembled in a RAID1 array (/dev/md0).
A few days ago I mistakingly unplugged the power connector of one of
the disks while the machine was running, but did not noticed it
immediately. The RAID array continued to run in degraded mode. Then
I tried to see what had happened with the failed disk and ran some
commands such as smartctl, hddtemp, ... The kernel displayed many
error messages such as this one:
Mar 15 07:54:08 jophur kernel: ata1: command 0xb0 timeout, stat 0xd0 host_stat 0x0
Mar 15 07:54:08 jophur kernel: ata1: translated ATA stat/err 0xd0/00 to SCSI SK/ASC/ASCQ 0xb/47/00
Mar 15 07:54:08 jophur kernel: ata1: status=0xd0 { Busy }
Mar 15 07:54:35 jophur kernel: ata1: PIO error
Then, at some point, the machine locked-up and later I found this dump
in the logs:
