Re: intel8x0 driver motorboots (gets caught in loop) in Quake 3

[Josh Buhl <uzs33d@uni-bonn.de>]

Doesn't look like we're getting very far in this thread...

I, like Dmitry, am eager to help debug this problem and can 
patch/compile/use gdb, but don't know much about alsa internals. Anybody 
have any hints about what to try next?

"When you wake up in the morning, Pooh," said Piglet at last,
"what's the first thing you say to yourself?"

"What's for breakfast?" said Pooh.  "What do you say, Piglet?"

"I say, 'I wonder what's going to happen exciting today?'" said Piglet.

Pooh nodded thoughtfully.  "It's the same thing," he said.
