I hate to post a "me-too", but here it goes.  I'm also experencing similar
problems with pcm on my laptop with the neomagic driver.  Running "amp
-s" which reports the number of frames written to the sound device, will
write about 20 frames, and then hang in the state of [pcmwr] until ctrl-c
is pressed.  It sounds like theres a DMA transfer problem.

Doing something like "cat /kernel > /dev/audio" will also just loop the
first 1/2 second over and over.
