> Yep, thanks. I found this while trying Thomas Gleixner's cyclic test over the POSIX skin (http://www.tglx.de/projects/misc/cyclictest). After fixing a rather ugly bug in his code (missing mlockall) I ran into a yet unknown issue with the POSIX skin: the code just hangs when wrapped to Xenomai. Compilation: gcc -o cyclictest cyclictest.c <posix-cflags> <posix-ldflags> Invocation: cyclictest -n -p 99 Maybe its just real-time starvation (but the watchdog doesn't trigger, and I do not see why it should starve), maybe its a crash (will try to attach a serial console later). Anyway, it's an easy test case (and also a nice tool), so you may want to have a look as well. Jan
