2.6.35-longterm review patch. If anyone has any objections, please let me know.
------------------ From: Stefan Richter <stef...@s5r6.in-berlin.de> [ upstream commit 7f7e37115a8b6724f26d0637a04e1d35e3c59717 ] When firewire-ohci is bound to a Pinnacle MovieBoard, eventually a "Register access failure" is logged and an interrupt storm or a kernel panic happens. https://bugzilla.kernel.org/show_bug.cgi?id=36622 Until this is sorted out (if that is going to succeed at all), let's just prevent firewire-ohci from touching these devices.
