Re: next-0519 on thinkpad x60: sound related? window manager crash

Thanks, so something still missing in the mmap handling, I guess.

I've worked on two different branches for potential fixes of your problems. Could you test topic/dma-fix and topic/dma-fix2 branches? git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git Just pull one of them onto Linus' git HEAD.

I guess we'll go with David's new patch, but still it's interesting whether my changes do anything good actually.

On torvalds 623f6dc593, topic/dma-fix causes sound to be output as alternating half-second bursts of noise and a few seconds of silence. topic/dma-fix2 appears to work properly.

Thanks, Alex.
