From: Stefan Richter Date: Tue, 7 Dec 2010 18:16:02 +0000 (+0100) Subject: firewire: ohci: fix regression with VIA VT6315, disable MSI X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=af0cdf4947818becfe209610b209315578645ab4;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git 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.
