Subject: oops 2.5.46 snd_timer_free
Date: Tue, 5 Nov 2002 18:34:52 +0100 [thread overview]
Message-ID: <20021105173452.GA659@wonderland.linux.it> (raw)
This happened after I run rmmod the second time: it segfaulted and the
system locked up after about one second.
(missing do_select symbol is my fault)
