[Bug 366352] Re: kernel-rt freeze after new install jaunty studio

[Philip]

mixed results with the new kernel. First, the cpu is corrected. However,
when I took the next step and added @audio - memlock 512000 to my
limits.conf, Jackd crashes, leaving a defunct jackd process and
unresponsive qjackctl, taking my gnome toolbar with it. Or rather it
fails to start jack and the toolbar disapears anytime I click on it with
my mouse. If I uncheck the lock memory option in qjackctl, it works
well. Hmmm, I just tried the same thing with the generic kernel and the
same thing happens. I'll pursue that separately.

Also I am seeing lots of this from dmesg with this kernel
