[Bug 193578] Re: Scrolling Firefox interrupts Rhythmbox audio

I just booted 32-bit final jaunty, then I ran "sudo aptitude remove
pulseaudio" and selected "log out". After 10 seconds the user "ubuntu"
logs back in automatically. I started the song in totem again and then I
double checked in terminal that "ps aux | grep pulse" returns nothing.
Then I ran the x11perf repro I described above and boom the bug happens.

I don't think it's pulseaduio, I think it's either a general kernel
regression or its the new intel driver which has a kernel component to
it (i915 and drm modules). Maybe one of these graphcis related kernel
components floods the kernel with ultra high priority interrupts or
tasklets or whatever they call it in kernel land. This way the audio
requests just gets ignored.

Maybe some uber kernel ninja can run sysprof or whatever tool is suited
to find out why audio skips??
