Hrm... looks like it could be X and the framebuffer walking on eachother toes, not sure tho, 2.6.12-rc2 is supposed to have patches fixing such ... > 3. I configured sound to use snd-powermac.

Yes, the Alsa code isn't doing very well when sleep is triggered while an application is playing.

Possibly, I haven't really checked what's going on with suspend to disk.
