Did you make it?

I was able to repeat it a few times now. Just run xmms with
an MP3 radio
live-stream in background. Then compile a few packages, or
download some
files with firefox.

BTW, seems that the lockup is not  instantly. The last two
times I observed
that it takes 1 or 2 seconds where the mouse-pointer becomes
very slow and
starts jumping, before everything freezes.

But the music keeps playing, which means that the network
still works
(although I cannot login).

No deadlock here.

I did build a lot of stuff over nfs with audio playing.

Hmm, I sometimes see that with some process bombing the
kernel with  
system calls. But that's no deadlock, it just responds very,
very  
slowly.

Can you reproduce this with something else than playing an
audio  
stream? It looks more like a process running amok than awacs
acting  
up right now.

have fun

FWIW, I can't reproduce this either.  I compiled zsh while
listening to 
an internet radio station.  Compile finished 25 minutes
later without any
problems.  The system is a dual 450MHz G4 Powermac running
NetBSD 3.1 stable.
