Your bug is completely different issue. Whatever you are point to redhat
bugzilla is with respect to SAS controller.

In your case it is FC controller.

You have mentioned that 
"Latest kernel known to work: 2.6.26 from Debian Backports"

Can you provide me driver version where things are working fine. In case of
some working kernel is there, I would like to simply upgrade MPTFUSION driver
(do not upgrade a whole kernel). This way I would like to change only one
component of the system at a time...

This will help to understand where things are broken.

FYI,
MPTFC drive is highly in mentionation mode. There are very very minimal changes
happened to MPTFC driver since 2008.

Last change went to upstream for MPTFC is

Thanks, Kashyap
