Public bug reported:
After dist-upgrading to intrepid, Ubuntu appears to hang when shutting
down. I have traced this down to the ALSA shutdown script taking more
than a minute (!) to save sound card state. More specifically:
[EMAIL PROTECTED]:~$ time amixer -c0 -q set Mic 0% mute
real 0m8.061s
user 0m0.003s
sys 0m0.012s
This is reproducable only in single-user mode. When I run the amixer
command when logged in into X (I can even run the command from a
console, as long as X is running), the same command takes only a few
milliseconds as it should. I will attach an strace log from above call.
Of interest is the following line:
4.013297 ioctl(5, FIONREAD, [37]) = 0
which occurs twice in the script. It seems to be expecting data from a
network socket, but I can't figure out why.
On a side note: why is amixer doing dns resolution, or any network activity for
that matter?
