Weird message, I can not seem to find it in xenomai sources. Anyway the
message indicates that you should look at what is at 0x892160

You mean you are calling something like "wake_up" from a real-time
interrupt ? If this is what you are doing it can not work for obvious
reasons.

If you want to do that, you should use an rtdm_nrtsig object. Use
rtdm_nrtsig_pend in the interrupt handler, and call wake_up in the
nrtsig_handler.
