Hi list,
I am getting this timeouts:
pcm0:virtual:0: play interrupt timeout, channel dead
on a 6.1-PRELEASE Machine (just tested with ich.c from CURRENT too)
with this card:
pcm0: <Intel ICH5 (82801EB)> port 0xd800-0xd8ff,0xdc00-0xdc3f mem 0xfd201000-0xfd2011ff,0xfd202000-0xfd2020ff irq 17 at device 31.5 on pci0pcm0: <Avance Logic ALC655 AC97 Codec>

Any ideas, what's going on?
