Hi there!

On our AMD64 machines equipped with old Adaptec 2200S controllers, we
experienced a regression when updating to 2.6.25. The machines won't
boot anymore (in a reasonable time), but instead spit out tons of those
messages:
aac_srb: aac_fib_send failed with status: 8195

This is already reported in quite some places including LKML:
http://lkml.org/lkml/2008/5/12/365
https://bugzilla.redhat.com/show_bug.cgi?id=450444
https://bugzilla.redhat.com/show_bug.cgi?id=453472
http://www.linuxquestions.org/questions/red-hat-31/aacsrb-aacfibsend-failed-with-status-8195-651078/
http://forums.gentoo.org/viewtopic-p-5077382.html?sid=a51c3a0fba6aa854c0b49b8fae5cc15a

We found that this regression seems to be introduced by the bugfix
"aacraid: fix driver failure with Dell PowerEdge
Expandable RAID Controller 3/Di":
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=94cf6ba11b068b8a8f68a1e88bffb6827e92124b

By simply removing the quirk flag for our controller, we could boot again.

We did some quick stress tests on an AMD64bit machine with 16GB of RAM 
and saw no problems after this change:

Can this be safely changed/merged? Or is this the wrong way to fix it?

Please note that we also have machines equipped with newer Adaptec 2230S
controllers (PCI ID 9005:0286) which run perfectly with the current driver.
