Instead the 2.6.37-9.22~ppa1 one's have RT_GROUP_SCHED disabled.

Anyone could test those?

Ciao,

On Natty, 2.6.37-9.22~ppa1, Virtualbox

...

I confirm 2.6.37-9.22~ppa1 from abogani PPA (RT_GROUP_SCHED disabled) works fine.

AFAIK the *.33 kernel from abogani, CONFIG_RT_GROUP_SCHED=y, works fine (using audio.conf instead of limits.conf).

(All though I have an issue with installing a package like libboost-dev, which takes minuts when booted a RT kernel and seconds when using the generic kernel, Ubuntu and Debian, kernel 2.6.33.7-rt2. The Debian RT kernel has RT_GROUP_SCHED disabled though...,

BTW the kernel for Tango Studio has it also enable afaik

grep -i RT_GROUP_SCHED /boot/config-2.6.32-25-lowlatency
CONFIG_RT_GROUP_SCHED=y

Lucid here. Does this whole story apply to Ubuntu 10.04 also?
