Confirmed! [EMAIL PROTECTED] :/root# cat /proc/xenomai/sched CPU PID PRI PERIOD TIMEOUT STAT NAME 0 0 99 0 0 R ROOT 0 837 99 9999312 0 X TASK1 0 838 0 10999998 0 R TASK2 So far "only" on real hardware (P-I 133) with CONFIG_M586 and (this is likely also very important) CONFIG_PREEMPT. I'm now about to check if I can migrate this problem into qemu and/or capture it with the I-pipe tracer.
