Could you explain a bit more in details what this crash means? That there is a conflict between Linux and Xenomai using the same IRQ line should be detect by Xenomai, and you should find a note about the line now being disabled in your kernel log. Of course, you still need a chance to dump this log. Does the system really lock up completely (which it must not!)? Or do you happen to use a USB keyboard which may then suffer from the dead USB IRQ? > > I read that rt_e1000.ko now supports shared interrupts. Is this not the > case for rt_eepro100.ko? Please read the Xenomai FAQ on shared IRQs: http://www.xenomai.org/index.php/FAQs If something remains unclear, I could try to improve the explanation. Jan
