sorry, that I was not clear, kernel was sure fine, because I was  even 
able to call to echo(), but sound was extremelly jerky, that was 
probably caused by cpu overloading, remote ssh to machine was not possible,
months before I was run asterisk under normal priority, and it works fine,
I did only two things, realtime asterisk priority using -p switch and 
load module res_timming_pthread for timing source...
