[LAU] qjackctl freeze badly with lucid rt kernel 2.6.33-8

Hi folks, I'm on Lucid 10.04. I installed the rt kernel 2.6.33-8 from here [1], because the new nvidia driver doesn't like the rt 2.6.31. Now, with the new rt kernel qjackctl starts fine, then the gui crashes after about 1 minute, and qjackctl.bin freeze in the background. Then I have to shut down my machine pressing the halt button, because everything is frozen (cannot launch a terminal, nor type in it if it's open). It happened 7 times over 7 trials. This makes it unusable. And I need the new kernel to do audiovideo stuff with my nvidia card. Any hint? I read that this kernel has some problems with PulseAudio, but I don't know if this could relate to qjack. many thanks in advance!
