Hello,
My x86_64 systems has some trouble loading some ALSA snd-* modules since
the upgrade to 3.10.[01]: Several automatic modprobe calls hang, but
loading snd-intel-hda and snd-audio-usb by hand still works.

In /var/log/daemon.log I find the following messages:

This is a Debian sid system
# modprobe -V
kmod version 9
# echo t >/proc/sysrq-trigger
produces too much output to include the modprobe processes. I already
stopped most processes, but that is not enough.

Is this a know bug or has someone seen similar problems?

Not a known problem to me, at least. Perhaps it's a dep loop somehow.

This was first, and it's waiting. Which means it must be doing
something weird, because snd_seq_oss is loading now:

Perhaps in the tangle of modprobe install commands somewhere this gets
invoked?

On my systems, that's snd-seq-dummy, which depends on snd_seq. Which,
in fact, is already loaded.
Lucas, any clues?
Full quote below.

First thing to check is the /etc/modprobe.d/*.conf file that contains
these install commands. Did they change besides the kernel upgrade?

Not really related to this, but... people/distros should stop using
install commands for things like this. By using softdeps kmod is smart
enough to detect and (possibly) break loops. With install commands it
can't because it has no idea what the install command will do.

Searching kmod's log, I guess Debian still has:
install snd_seq modprobe --ignore-install snd-seq $CMDLINE_OPTS && {
modprobe --quiet snd-seq-midi ; modprobe --quiet snd-seq-oss ; : ; }

Weird... this is coming from a request_module(). Greping... this
should only be coming from
git grep request_module | grep snd-seq-client

Philipp, which kernel are you upgrading from? I don't see anything to
blame in the changes for the past releases. Any chance a bad entry in
your .conf was added too? You may want to paste the output of modprobe
-c, at least until "# End of configuration files. Dumping indexes
now:"

I don't think I could help, but we need more data, like the ones above.

I remember that someone reported it being Debian specific snd-seq-oss
loading stuff.

Likely, but I wonder what triggered a bug suddenly on 3.10.
There is absolutely no change in sound/core/seq/*, and through a quick
look, I couldn't find any suspicious change in kernel/module.c that
may lead to this problem between 3.9 and 3.10.
Philipp, can you get a sysrq-T trace while the stall?
thanks,

I've finally been able to reducte the number of processes to get a full trace; see attached file.
Please note that in this case the proprietary "nvidia" module was loaded, since I currently onyl have remove access to the machine.
The original trace from yesterday happend without the nvidia module ever being loaded.

Not that I know of: Booting 3.9.9 works fine, 3.10.x shows the problem.
...

I just upgraded from 3.9.9 to 3.10.0; also tried 3.10.1 which did not improve the situation.

Could you check the patch below? It makes the code path involving
with request_module asynchronous.

Subject: [PATCH] ALSA: seq-oss: Initialize MIDI clients asynchronously
The recent report showed that the initial registration of OSS
sequencer clients stuck at loading the sound modules, which involves
with request_module() at the init phase. As a workaround, call the
registration part asynchronously. (And, this is a better approache
irrespective of the hang fix.)

hum... it looks like a loop between the modprobe calls and the
request_module(), done in snd_seq's init. The request_module() call
will end up trying to load snd_seq again and it will remain waiting on
kernel/module.c:add_unformed_module().
In kmod we don't trust a COMING state on sysfs to avoid calling
(f)init_module() because a) the previous call may fail and b) it's
racy.
Changing the request_module() in the module to be async would solve
the problem (what Takashi Iwai did)... but this has been a
little controversial in the past. Rusty, what do you think? Maybe in
kmod we can take the COMING state into consideration for
*dependencies*? Or is moving that call to a worker acceptable?

With the patch applied all modules were loaded successfully: no hanging
modprobe processes anymore.
Thank you for your support.

Yes, add_unformed_module makes the same call. I think the answer is
simply "don't do that".

I thought about adding a post_init() call for modules for this kind of
thing, but it's actually pretty rare. Open-coding it seems fine.

Yes, add_unformed_module makes the same call. I think the answer is
simply "don't do that".

I thought about adding a post_init() call for modules for this kind of
thing, but it's actually pretty rare. Open-coding it seems fine.

problem (as little as the patch size is), so I'm going to apply my
patch as is for now.
