Subject: usb alsa oops in 2.6.28 in snd_mixer_oss_notify_handler
Date: Fri, 9 Jan 2009 19:26:53 +0100 [thread overview]
Message-ID: <20090109182653.GA12123@basil.nowhere.org> (raw)
Just got this oops in ALSA with 2.6.28 when I pulled a usb
sound device while something was writing to it.
It looks like it jumped to Nirvana through a bad function
pointer.
