Instead the 2.6.37-9.22~ppa1 one's have RT_GROUP_SCHED disabled.
Anyone could test those?

I don't think so... but the default kernel in 10.04 doesn't work so well
latency wise... I reccomend the ones in falktx's ppas....

works fine.

It would be useful for people who have a problem in this area to run
ps -O cgroup
so that we can see what cgroups are in use on their systems.

Doesn't work with the "-" here in Gentoo. (bogus syntax error)
ps O cgroup
seems to work ok though.

No cgroups seem to be in use here (FC13 i386), a "-" appears under that
column. The kernels do have CONFIG_RT_GROUP_SCHED=y
