I wonder if I
could force the USB bus to another IRQ or if I could
move eth0 and yenta to another IRQ.
This is the part that I am afraid is hard wired, at least on most
laptops.
I can unload yenta and the module for the internal card which already
enhances the behaviour of JACK.
Additionally I installed the rtirq script of Rui Nuno Capela (thanks a
lot BTW).
But still I hope I can decrease latency on my system, but it's not
urgent so many thanks for all hints I got from this list. I learned a
lot and fixed some errors on my machine during this weekend.
Best regards
