So when I build a kernel-rt ex 3.0 from kernel.org source I need to use

boot option threadirqs, if it isn't patched?


On AV Linux I run the 3.0.23-avl-7-pae with and the self-build

3.0.23-rt40 without threadirqs. This way there's no difference between

those kernels. I can't make music using JACK1 (didn't test JACK2 until

now with AV Linux).


But at least kernel-rt < 2.6.39 are ok without threadirqs ;)?


But CONFIG_IRQ_FORCED_THREADING has to be set for a kernel-rt too?

spinymouse@precise:~$ grep FORCE /media/avlinux/boot/config-3.0.23-rt40

CONFIG_IRQ_FORCED_THREADING=y
