Hi,
I'm running debian unstable on my PC. With kernel 2.6.5-rc3 the shutdown hang
while unloading ALSA modules. PC is alive (ie. responds to ping and to SysRq).
This is from lsmod:
snd_pcm_oss 51492 0
snd_mixer_oss 18752 1 snd_pcm_oss
snd_intel8x0 32004 0
snd_ac97_codec 59268 1 snd_intel8x0
snd_pcm 95204 2 snd_pcm_oss,snd_intel8x0
snd_timer 25668 1 snd_pcm
snd_page_alloc 11140 2 snd_intel8x0,snd_pcm
snd_mpu401_uart 7360 1 snd_intel8x0
snd_rawmidi 24736 1 snd_mpu401_uart
snd_seq_device 8264 1 snd_rawmidi
snd 54884 9 snd_pcm_oss,snd_mixer_oss,snd_intel8x0,snd_ac97_codec,snd_pcm,snd_timer,snd_mpu401_uart,snd_rawmidi,snd_seq_device
Alsa script is unloading everything:
for i in $(lsmod | awk '/^snd/ {print $1}'); do
$rmmod $i >/dev/null 2>&1 || :
done
I can reproduce using "rmmod snd_intel8x0", and this is the relevant part of SysRq-T:

In case it does matter udevd (from udev 0.024-2) is running:

Any clue?
