You don't seem to have a way to let jackd run with elevated
priority yet. This should be your first priority, because even with a
realtime kernel you will get horrible latencies, unless you fix that.
(IMO not a lot of people really need a RT-patched kernel nowawadays.)

So you should first install *and configure* a rtlimits-enables libpam
or use the set_limits command line app to start jackd, if you cannot
find one. But Ubuntu should have a libpam even for AMD64. (Btw: Do you
really want to run AMD64?)

Ciao
