I tried out a few of the schedulers and none of them helped the problem.
If anything I'd have to say it got worse.

As a final test I have switched to the kernel that was installed originally
by Ubuntu (2.6.24-24-server).
The problem still exists and I know for sure it didn't when things were
first setup.
- There's just no way we could have migrated 400gig of data onto the RAID if
it was this flakey.

Whatever it is is hardware related, and it seems to be getting worse over
time...
