Date: Sun, 10 Jul 2011 00:23:03 +0200 From: Stefan Richter Subject: firewire: ohci: do not bind to Pinnacle cards, prevent 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.
