debian-user:
I have a new machine with debian-6.0.5-amd64 and:
Intel i7-2600S processor
Intel DQ67SW motherboard
Intel 520 Series 60 GB SSD
I noticed error messages similar to the following example on the console:
[ 131.742744] ata3.00: exception Emask 0x10 SAct 0x0 SErr
0x400100 action 0x6 frozen
[ 131.742787] ata3.00: irq_stat 0x08000000, interface fatal error
[ 131.742806] ata3: SError: { UnrecovData Handshk }
[ 131.742822] ata3.00: failed command: WRITE DMA EXT
[ 131.742839] ata3.00: cmd 35/00:00:c8:ce:79/00:04:00:00:00/e0
tag 0 dma 524288 out
[ 131.742840] res 50/00:00:c8:ca:79/00:00:04:00:00/e0
Emask 0x10 (ATA bus error)
[ 131.742886] ata3.00: status: { DRDY }
I assume these are error messages coming from the disk device driver
(?). What do they mean?
I then upgraded the kernel to 3.2.0-0.bpo.2-amd64 via debian-backports,
and the errors filled the console whenever the disk was busy (such as
running tasksel and installing Graphical desktop environment).
STFW, I installed sysfsutils and added the following entries to
/etc/sysfs.conf. The quantity of messages decreased:
block/sda/device/queue_depth=1
block/sdb/device/queue_depth=1
Any suggestions?
TIA,
David
