What does "modinfo 3w-9xxx" give you?

The driver for release is[fw].  If you're
not running that version, grab the driver source and rebuild,
add the module to your tree and create a new initrd.  If you
need some help in doing that, just let me know.

I haven't deployed but one (1) system with a 3Ware Escalade
9500S, so my exposure to the 9500S line has been limited.  I
have deployed countless Escalade 6000-8000 series products

Yeah, it looks like it is probably unrelated to the 3Ware
card.  But still, take the time to read the whitepaper on
performance with the 9000 series -- and the couple of tweaks
they recommend.

The Linux kernel VM/buffer defaults _never_ assume there is
an on-board storage intelligence that can command and queue a
lot closer to the hardware than it can.  ;->
