Yuck, I guess this is on the new Hammerfall right? Not much I can do
save for trying a newer version of alsa cvs to see what happens. Maybe
this should be reported on alsa-devel. "pcm.c" sounds like the generic
pcm code inside the alsa driver package, most probably some bug in the
Hammerfall code is triggering this?

Have you tried other alsa applications that play sound through alsa
other than jack and alsaplayer?
