Not sure if this helps. I'm getting this reset with 2.6.21-rc4.
After the reset the controller seems to work again.

That one looks like a drive-side issue. CPB resp_flags 2 indicates the
drive accepted the command and the controller is still waiting for a
response.
Could be that this is another drive that needs to be added to the NCQ
blacklist, some similar Maxtor models seem to have issues..
