Please tell us your Xenomai and I-ipipe patch version. Also your kernel
=2Econfig my be helpful. Do you use any "special" Linux drivers, e.g. som=

binary-only nvidia or ati stuff?

Can you derive a simple demo code from your application so that we can
give it a try as well? I have an emulator here (qemu) where I can easily
step into such issues (when they trigger on my box too...).

If you want to dig deeper on your own: there is a kgdb add-on patch
available for 2.6.16 (not 2.6.17 as falsely claimed by the readme) [1].
