2.6.36-stable review patch. If anyone has any objections, please let us know.
------------------
From: Stefan Richter <stef...@s5r6.in-berlin.de>
commit af0cdf4947818becfe209610b209315578645ab4 upstream.
"VIA Technologies, Inc. VT6315 Series Firewire Controller [1106:3403]"
does not generate any interrupts if Message Signaled Interrupts were
enabled. This is a regression since kernel 2.6.36 in which MSI support
was added to firewire-ohci. Hence blacklist MSI on all VIA controllers.
