That sounds like you're sources are still misconfigured. I had this
effect on an AMD system as well, and only with SuSE 9.0. The symptom was
some unresolved symbols when trying to load the reiserfs module,
resulting in a kernel panic at boot time because the root fs could not
be mounted. Try a "make mrproper" in /usr/src/linux and go through the
entire configure/build process again. You should be able to get more
info by scribbling down the kernel panic message and googling for it.
Good luck!

The cap patch lets you run jackd (using the jackstart wrapper program)
with realtime priorities without having to run it as root. If jack does
run as root (using sudo, setsuid or whatever) you get the same effect
without having to patch the kernel.
On my SuSE 9.0 system, this makes a *great* difference. I still have
some gripes using SuperCollider with Jack, when the system is under high
load, but all in all Jack runs very smooth at low latencies.
