Subject: [BUG] 3.10.[01] modprobe snd-... hangs

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.

# ps axf

...

 1119 ?        S      0:00 sh -c /sbin/modprobe --ignore-install snd-rawmidi && { /sbin/modprobe --q
 1148 ?        S      0:00  \_ /sbin/modprobe --quiet snd-seq-midi

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?
