Hello,
I'm not sure if I'm not off topic.
We use Linux 2.6.24 and Xenomai 2.4.1. Occasionally (once in few days) we get an kernel panic and I don't know If it's our fault or a problem of kernel/xenomai/adeos/configuration/hw/...
If you have any questions, i'll try to answer them. Any help is welcome.

I will try to reproduce the log (visible part of it). I can mail you snapshots for details, if needed:
