You still haven't had a response ;)  Let's add a cc.

Oh, you reported it against 2.6.23-rc4-mm1
(http://lkml.org/lkml/2007/9/1/92) and I did cc linux-ide in my response.

I'll continue to point out where this sort of thing occurs because last
week I was told that a reson why so many bug reports are ignored is because
"linux-kernel has too much traffic".

Andy is using qla1280.  You're using sata.  So it's probably a different
bug, with the same symptoms.

Can you please confirm that this bug is present in -mm and not present in
