harddisk or kernel problem?

[Nico Schottelius <nico-kernel@schottelius.org>]

Hello!

Since yesterday I have the problem that at bootup my cryptoloop (/home) does not
get mounted anymore. These messages are produced by the kernel:

---------------- snip ------------------

Freeing unused kernel memory: 140k freed

if I log in as root and issue `mount /home`, it works:

---------------- snip ------------------

XFS mounting filesystem loop0
Ending clean XFS mount for filesystem: loop0

---------------- snap ------------------

Yesterday the errors
 `hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }`
repeated (don't have the dmesg, forgot to dump kernel messages).

Now I am trying the following:
enabling Anticipatory I/O scheduler (additionaly to the Deadline I/O
scheduler) and disabling Vector-based interrupt indexing.

This is just a guess, can someone tell me if that is senseless or if my
harddisk is most likely broken?

Attached dmesg from 'running' system and the new .config (changes see
above) I made.

Help is very much appreciated,
