If unsure where the problem comes from, try to boot a clean kernel (unpatched) first, then a patched one but with disabled ipipe, and then one with disabled xenomai. If the bug seems to be ipipe/xeno-related, please report the patch and the xenomai versions, and also any potential board-specific patches. Jan
