Comment 61 for bug 87652

At this stage, I haven't reproduced that. Paul Mackerras has a QuickSilver and tells me that with current upstream, sound seems to work just fine... I'm a little bit at a loss trying to understand what is happening, it would help if I could reproduce of course.

We could implement support for recovering from DEAD in snd-powermac I suppose. But that's probably just the consequence of something else. I wonder if maybe we are tweaking the DBDMA lists the wrong way around or something like that.

Is that specific to CONFIG_PREEMPT or some HZ setting ?
