I cannot reproduce those messages after turning nucleus debugging on. Instead, I now either get relatively more failing mutexes or even hard lockups with the test program I sent to you. If the computer didn't crash, dmesg contains 3 Xenomai messages relating to a task being movend to secondary domain after exception #14. As when the computer crashes: I have written the last kernel panic message on a paper. Please tell if you want also the addresses or (part of) the call stack.
I'm still wondering if there's a programming error in the mutex test program. After I sent my previous message, and before I turned nucleus debugging on, I managed (by reducing the sleeptimes to max. 5.0e4) to fatally crash the computer, while spewing out countless 'scheduling while atomic messages'. Is the mutex error reproducible ?
Tomorrow I'll try the patch.
