I have attached mplayer8251.strace, which is from a custom 2.6.15 kernel on
Debian. The problem exists on other 2.6.15-kernels tested, as well as on a
box running Mandriva 2006.

Other media players fail in similar ways, either crashing or going into an
endless loop.

Seeing the same problems as above. Have tried with several 2.6.14 and
2.6.15 kernel variants and alsa-drivers standalone on my gentoo system. 
Fails with xmms, mplayer, cat /dev/urandom > /dev/dsp, etc.
I can't really add more than what is already said, but if there is any
experimental code you wish to have tested I can try it.
