[LAU] : tons of delay of 5667.000 usecs exceeds estimated spare time of 5298.000; restart ...

Hi, I just bought a Native Instrument Audio Kontrol 1 Usb2 and I got some strange problems with it. I made some test. Some times it works perfectly, and other times I got this type of messages in qjackctl : delay of 5667.000 usecs exceeds estimated spare time of 5298.000; restart ... It doesn't seem to directly affect the sound. I am running a 2.6.25.8-rt7 kernel with Jack-0.116.1 I don't really understand what happens. Some other times the sound become totally crappy. And the last strange behaviour I noticed is when I use PD. When I open some of my patchs, but not all, the audio connexions of my sound card disappear in qjackctl, jack is totally blocked and I can't kill it even with "killall -9 jackd" command. I have to reboot. I tried with a 2.6.26 kernel and it does the same. Any experience or hints to help me ?
