Description Nicolas Mailhot 2013-05-10 07:08:33 EDT
Additional info:
[ INFO: possible recursive locking detected ]
3.10.0-0.rc0.git24.1.fc20.x86_64 #1 Not tainted
pulseaudio/1124 is trying to acquire lock:
 (&(&substream->self_group.lock)->rlock/1){......}, at: [<ffffffffa01e14f3>] snd_pcm_action_group+0xa3/0x240 [snd_pcm]
but task is already holding lock:
 (&(&substream->self_group.lock)->rlock/1){......}, at: [<ffffffffa01e14f3>] snd_pcm_action_group+0xa3/0x240 [snd_pcm]
other info that might help us debug this:
 Possible unsafe locking scenario:
 *** DEADLOCK ***
 May be due to missing lock nesting notation
4 locks held by pulseaudio/1124:
 #0:  (snd_pcm_link_rwlock){......}, at: [<ffffffffa01e31c7>] snd_pcm_drop+0x57/0xe0 [snd_pcm]
 #1:  (&(&substream->self_group.lock)->rlock){......}, at: [<ffffffffa01e31cf>] snd_pcm_drop+0x5f/0xe0 [snd_pcm]
 #2:  (&(&substream->group->lock)->rlock){......}, at: [<ffffffffa01e2ff1>] snd_pcm_action+0x31/0xa0 [snd_pcm]
