Over the last few days I've been having problems with arecord.
Basically it writes the file header, prints its status line and then hangs
at 100% CPU usage. Forcing a coredump reveals:

I'm using kernel 2.4.10 with the low-latency patch, current CVS ALSA
drivers, libs and utils, Midiman Audiophile card.
snd built with ALSA 0.9 support records OK, so it's probably not that deep
down, but I can't see anything really glaring.
Using the hw:0 device gives an i/o error.
aplay is fine.

I have done a full rebuild (make cvsclean or distclean and then
cvscompile).
TIA for any clues what I've done or what's gone wrong.
