I have seen this problem with the 2.6.33 kernel in Fedora 13. The
problem goes away in 2.6.35-rc3. (Though networking is fubared for me on
that kernel, so I have not migrated to it.)

My understanding is the "fix" in the driver was to blacklist ncq for
that controller. I have not verified that yet.
