After Upgrade kernel to 2.6.29-gentoo-r5 the alsasound init script does not end. My Laptop cannot clearly shutdown with this kernel. Sondcard is "HDA Intel" Reproducible: Always Steps to Reproduce: 1. compile a 2.6.29 kernel with snd_hda_codec_* modules on a pc with intel hda soundcard. 2. alsasound is in default runlevel 3. start and shutdown this pc # /etc/init.d/alsasound restart * Storing ALSA Mixer Levels... [ ok ] * Killing processes using ALSA... [ ok ] * Unloading ALSA modules... With the new kernel a lot of new snd modules exist: snd_hda_codec_*. This modules are in use and cannot be unloaded. -> The alsa script cannot end.
don't use module unloading (discouraged in ~ version of alsa anyway)
Thanks, disabling unload modules helped for me. Now i can normaly shutdown with the new kernel.
Same is here. Actually, in my case it is one module snd_hda_codec_analog that is the show stopper. And look at cat /proc/modules snd_seq 32192 0 - Live 0xffffffffa00bd000 snd_seq_device 3348 1 snd_seq, Live 0xffffffffa002f000 snd_hda_codec_analog 62112 1 - Live 0xffffffffa009e000 snd_hda_intel 14744 0 - Live 0xffffffffa0089000 snd_hda_codec 35152 2 snd_hda_codec_analog,snd_hda_intel, Live 0xffffffffa00f7000 snd_pcm 42568 2 snd_hda_intel,snd_hda_codec, Live 0xffffffffa007c000 snd_timer 12944 2 snd_seq,snd_pcm, Live 0xffffffffa0055000 snd 35480 7 snd_seq,snd_seq_device,snd_hda_codec_analog,snd_hda_intel,snd_hda_codec,snd_pcm,snd_timer, Live 0xffffffffa0039000 snd_page_alloc 4992 2 snd_hda_intel,snd_pcm, Live 0xffffffffa0006000 snd_hda_codec_analog shows that it has one dependency (1) but no module using it are listed ! The model that depends on it is snd_hda_intel, so if it is removed first, the rest follows. So it is some bug that snd_hda_codec_analog has such 'hidden' dependency
this might be considered a duplicate of BUG253535, to workaround this problem changing UNLOAD_ON_STOP to no in /etc/conf.d/alsasound could be used (regardless of what sound card is affected and which is otherwise irrelevant). stabilizing a newer version of alsa-utils where this is the default would be a plus, as otherwise trying to remove the sound modules by reordering could reportedly result in a kernel race condition.
I was bitten by this bug, had found the workaround of disabling unload modules by myself and then finally looked at bugs.gentoo.org. *g* I do not agree with the severity of normal. After shutdown hangs it is necessary to push the power button. Because at this time the hds are still mounted, this could lead to a damaged filesystem. The severity should be critical.
