I sort of found the problem. Its most probably a bug in the rc4 or rc5
release of the snd-pcm-oss alsa module.

When I try to run pd without the -alsa flag when the snd-pcm-oss module is
not loaded, the machine does not freeze. When I try to run pd without the
-alsa flag, _now running alsa 0.9.0rc3_, the machine doesnt freeze either.
(Note, as a normal user!)

I have also tried it on a dell laptop running 2.4.7-something kernel, and
the same problem. (still as a normal user)

Anything else anyone wants me to try? (0.9.0rc4/cvs driver or something?)
