Subject: [git pull] FireWire update
Date: Mon, 11 Jul 2011 15:42:49 +0200	[thread overview]
Message-ID: <20110711154249.7b755dff@stein> (raw)

Linus, please pull from the movieboard branch at

    git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6.git movieboard

to receive the following quirks workaround for the IEEE 1394 (FireWire)
subsystem.  This is a hopefully temporary bandaid for a comparably rare
piece of hardware.

Thanks.

commit 7f7e37115a8b6724f26d0637a04e1d35e3c59717

    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.
