SRU Justification:

Impact: Audio and Video artifacts while system is under load, such as with trackerd or updatedb.

Fix Description: The 8.04 scheduler algorithm selected for x86/x86_64 -generic is USER_SCHED. CGROUP_SCHED is much better at load leveling between process groups. The -server flavour has used CGROUP_SCHED from the beginning and has been shown to not have this issue.

Patch: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=commit;h=273f7b551a420580307fa414fe616f0e276a4035

TEST CASE: Start a test sound using gnome-sound-properties (System/Preferences/Sound, select Sound Events Test). As another user (root) run 'find / -type f | xargs grep foobar'. Audio clicks and pops can be heard in some cases.
