The truth is, that it's not completely solved, there's at least the need
to switch the config script when using different kernel versions.
RTIRQ STILL IS
rtirq - Revision 7, resp. $ wget [snip] --2012-05-05 03:09:00--
First the drawback when using 1 config for both kernels, then
3.2.0-23-lowlatency with good prios and then 3.0.30 (lowlatency) with
good prios. Using nvidia-current-295.40 with both kernels.
Rebooting seems to be important, stop and start rtirq seems not to work.
