commit: 7f7e37115a8b6724f26d0637a04e1d35e3c59717 From: Stefan Richter <stef...@s5r6.in-berlin.de> Date: Sun, 10 Jul 2011 00:23:03 +0200 Subject: [PATCH] firewire: ohci: do not bind to Pinnacle cards, avert panic
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.
