Well, I just tried rosegarden, and I have the same issue : qjackctl crash,
and dmesg command output the same as you.
After that, If I try to run qjackctl again, it fails, or some times it runs,
but if I play some notes on Zynadd for exemple, the sound is totally crappy.
I have to reboot the system to solve this problem.
grrrrr
cheers,
