Hello again, I have though, that all my troubles with this kernel panic (see https://mail.gna.org/public/xenomai-help/2008-07/msg00054.html) are over, but suddenly it reappeared. The full log is in attachment. I used snapshot of screen, OCR program and manual correction, so expect possible errors in log. I haven't seen the error for months, I was believed that it was caused the combination of other two problems (hopefully already solved or evaded). But this kernel panic emerged during the weekend test, when we tested usability of a new motherboard for our purposes. It's perhaps not critical for me, but if you have any advices or questions, I'm listening. Thanks Petr
