OK. Connected a terminal to catch early kernel messages. Still no output unfortunately (with the regular kernel I do get output on the terminal, so the connection works). Meanwhile also built and tested kernel 2.6.32.15 + xenomai 2.5.4. Still nothing. I'm clueless. I'm running Xenomai for years on dozens of systems and I've never run into problems like this. I think I'll have to sit down and take a close look at what I'm doing. I've always built my kernels using make-kpkg, maybe that somehow introduces a problem here. I'll try without it. (unfortunately/luckily I have to work from home for a few days so I can't get to the test system until later this week) Theo
