That is wrong. If jack is running you should not see anything from
ardour.

Yup. Maybe as root? You should never use anything as root, there is no
need. Just start everything from the normal user (not root) that you
login as normally.

Usually you don't need to reboot. I don't know why jack is having
problems.

Unlikely (there is some basic problem with jack).

I also would be sick of rebooting if I were in your shoes!

You should try the simplest possible way to start jack first, from the
command line of a terminal:

jackd -R -d alsa -d hw:0

That should start it with 1024 frames per period, 2 periods at 44100 Hz
sampling rate. See what happens when you do that. The problems you are
having suggests some issue with the soundcard, specially the hung jack
processes. Always run jackd as a normal user (not root).

You could also look at /var/log/messages or the output of dmesg to see
if there any kernel error messages like "Oops" or "BUG" statements.
