Comment(by corbet):
Sigh, it would have been nice if it were so easy.
I've still not actually seen this problem. Is runin the only way to
provoke it?
One thing worth noting is that IRQ 48 is not just for audio; it is used
for every DMA controller on the system. That includes the video, memory-
to-memory, and peripheral DMA units. Any of them could be causing this
problem. Once I can reproduce it, I should be able to narrow it down
fairly quickly.
