 My problem have exactly the same behavior but with a very different sound 
 device.
 
 pcm0: chn_write(): pcm0:play:dsp0.p1: play interrupt timeout, channel dead
 
 The device is SiS 7018, using snd_t4dwave driver. I also tried to turn off 
 ACPI without luck. Perhaps my problem is related?
 
 Following is the playback output. Tried "dd if=/dev/random of=/dev/dsp" 
 too, getting same behavior. Do you think it helpful if I post more info 
 like dmesg and various hardware data?
