Most likely the RTC isn't used at all anymore, check how many times it
has fired with "cat /proc/interrupts". One my system it fires exactly
once during bootup.
AFAIK, the only important configuration nowdays is to make sure that
the soundcard (or usb hub is connected to) is executed first, then JACK
(which automatically gives the priority of your audio processing
threads). So I'd suggest to run the soundcard interrupt at a high
priority, say 95-97 or so (leave 99 for the housekeeping threads).
Then run JACK at 80 (which will run your audio processing threads at
75).

That doesn't look right. I am not sure that
changing this would fix
your problem, but I prefer to have a different RTPRIO for anything
above 50.
It has changed since that posting :)

I wonder if it makes a difference if the rtc is so low, One of the
web pages that was provided here mentions that rtc should be first.
