Shutdown pauses till ALSA times out.

I have been getting this too with an Intel 82801DB/DBL/DBM audio controller. (NEC VERSA M400)
I measured the shutdown stall as 2.5 minutes at the "Shutting down ALSA" line, followed by some rapid error messages before shutdown.
Todays update has made the PC go to a progress bar shutdown, pausing for some time at about 40%, but a lot less than 2.5 minutes

same problem here, but with

Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA)

and alsamixer shows me just onde level bar (master)...

I have been on a wireless connection over the weekend and their is no pause when it shuts down

**
It only pauses when i have a network cable attached
The issue is with the wired networking.

These errors show on screen during shutdown (Same as in the edit to my original post:

* Shutting down ALSA [OK]
* Stopping Bluetooth [OK]
* Stopping Avahi mDNS/DNS-SD Daemon avahi-daemon [OK]
* Asking all remaining processes to terminate... [OK]
NetworkManager: <WARN> dhcp_watch_cb(): dhcp client died abnormally

I can confirm this bug here on a Toshiba Satellite U400, Ubuntu 8.10, latest updates up to Oct 13, 2008.

Actually, I found a "solution" too. It works in my case:
In /etc/init.d/alsa-utils comment the line "mute_and_zero_levels "$TARGET_CARD" || EXITSTATUS=1" to "#mute_and_zero_levels "$TARGET_CARD" || EXITSTATUS=1". The mute_and_zero_levels call waits a very long time. In my case, I even thought it was forever.

By the way, I think it used to work about one month ago, but I'm not sure which alsa-utils version this was.

My report is also network related. The error messages after the long time out list dhcp client errors, so I don't think ALSA is really involved. My PC shuts down quickly on my office network, but takes minutes on an Aztech DSL router, so this bug depends on the dhcp server type

I can confirm the error, too. It is network related. My system hangs at "Shutting down ALSA" until
I use the hardware switch for Bluetooth/WLAN. After switching of Bluetooth/WLAN it works fine.

The same problem. Dell Inspiron 1501.
