Nothing after few minutes of waiting. Last lines I can see with
jack -v -R -d alsa:

20291 waiting for signals
load = 0.0094 max usecs: 4.000, spare = 21329.000

and then instant freeze. No respond to keyboard input, no luck with ssh..

Hmm.. it says also "required capabilities not available" :o
could it be the realtime-ls module after all...?
I load it with modprobe realtime allcaps=1 any=1
(tested also modprobe realtime allcaps=1 gid=18 , 18 == my audio group)

--jussi
