pulseaudio fails with video playback in recent kernel

Log file excerpt from start of pulseaudio problems to the time it quits after CPU overload
Pulseaudio initially seems to work but after a short while, or maybe under CPU load, the sound breaks up and stops, volume controls become ineffective. The CPU load seems to peak at this time and pulseaudio logs errors.
Seen using kernel kernel-22.214.171.124-213.fc11.i586
Goes away on reverting to kernel kernel-126.96.36.199-167.fc11.i586
I think it's also OK with kernel-188.8.131.52-191.fc11.i586
How reproducible: 100%
Steps to Reproduce:
1. using kernel-184.108.40.206-213.fc11.i586, pulseaudio, snd_intel8x0
2. start flash video playback (eg. youtube content)
3. wait approx 20 sec, sound breaks up and messages logged
Actual results: broken sound, ineffective volume control, CPU load rises
Expected results: smooth playback
Additional info: the login sound often stutters on this system, a while back it worked perfectly but has since returned to the stuttering state.

Some of the symptoms are the same (log messages) but the other bug doesn't mention serious problems with the sound quality, or that pulseaudio crashes, or the volume control not working.

Those are all caused by the overruns (pulseaudio commits suicide after it consumes excessive number of cpu time, which disconnects the volume applet).
