I get similar messages with my Gravis Ultrasound, but intermittently. I
have only been able to get them to happen while playing DOOM; normal
/dev/audio use doesn't seem to trigger it, although something possibly
related causes very infrequent and intermittent failures of programs
that use /dev/audio. However, in those cases the "DMA (output) timed
out" message doesn't appear; the program just says it failed to open
/dev/audio that time.

I know there aren't any IRQ or DRQ conflicts on my system, and I have a
busmastering SCSI controller that uses DMA and doesn't exhibit problems
of this sort. I also believe there was a time when the sound driver
didn't exhibit this problem, but sadly I can't remember exactly when I
saw the problem start.
