commit: af0cdf4947818becfe209610b209315578645ab4 From: Stefan Richter <[email protected]> Date: Tue, 7 Dec 2010 19:16:02 +0100 Subject: [PATCH] firewire: ohci: fix regression with VIA VT6315, disable MSI
"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.
