This does indeed look like a drive side issue to me (the controller is
reporting CPBs with response flags 2 which as far as I can tell
indicates it's still waiting for the drive to complete the request).
I have been using this hw-config (SATA II, NCQ) since the nvidia ADMA
support made it in the -mm kernel (maybe around 2.6.19-mm? or even
earlyer). I'm seeing this problem excessively since I upgraded to
2.6.21-rc3-mm1. I think something got broken recently...
Can you post the result of "hdparm -I /dev/sdX"?

That's a fairly recent drive. Does the problem go away if you downgrade
the kernel?
Yes, for me the problem was introduced recently. I have moved around terabytes
(sic!) on my discs with older kernels and I never got errors.
I may have missed the answer to this before, but: does the problem go
away if you disable preempt?
