Hi guys, I had same problem with CFS + BOINC + pulseaudio on my Pentium 4 HT
2.8GHz. The trouble was caused by using schedtool to run BOINC. After I removed
it (sudo aptitude purge schedtool), there was no pulseaudio stuttering (despite
pulseaudio is using 20% of my CPU... which is IMHO pretty

Dana, the linux task has been invalidated before.
Please refer to bug 188226 to improve the default kernel behaviour.
I just wanted to provide the workaround for boinc, which I'm using myself.
Dhaval has asked me to use the uevents interface instead, so I'll do a new
upload for boinc later, which
Aah, okay. Perhaps this bug just needs to be renamed back to being
specific to 'boinc' again, and not marked fixed yet since it's not yet a
'proper' fix.
I can confirm, by installing the old .22 kernel, that the audio dropouts
only happen with the new .24 kernel. It's especially noticeable with
Marking it as invalid, not really a bug with boinc.

I've filed a new bug 188226 for linux: Kernel should use
CONFIG_FAIR_CGROUP_SCHED.
I'll upload a workaround for boinc to adjust the cpu_share to 2 in the init
script until this gets resolved for the kernel.

One temporary solution to avoid ditching boinc or folding for those who
ran two processes on a dual core system is to run one process. You'll
lose some efficiency, yes, but the system doesn't become a hog.
