Problem solved! It was apparently coming from some kernel debugging feature that I activated in my configuration. I haven't identified precisely which one since I unset a couple of them at the same time.
Thanks Paul for your help and configuration file. It was really helpful. --Bruno 2009/1/20 Bruno Rouchouse <broucho...@gmail.com> > Hi list, > > I'm trying to get Xenomai to work on my Intel Core 2 Quad (x86_64) but I'm > facing a critical issue here and I'd like to know if someone has already > stumbled over a similar problem. > > *Problem: > *I experience a kernel freeze or spurious reboot as soon as I get "I-pipe: > Domain Xenomai Registered".
