Does backing out the following commit fix things?
commit d43744390e460dce6626fb8de2c02a24ff650005
Author: Alan Cox <alan@xxxxxxxxxxxxxxx>
Date: Mon Nov 30 13:22:54 2009 +0000
pata_cmd64x: implement serialization as per notes
Although quite unlikely, commit f0353813afe784330622596ff141e7525ccd99de
may also change things. Try backing that out, if backing out the first
commit (d43744...) fails to improve behavior.
