Have you been able to look at dmesg output (or /var/log/message) after the USB mouse and keyboard stop responding? This sounds very similar to an issue we had where a real-time PCI device was sharing an interrupt with one of the USB controllers. As a workaround, is it an option to simply use a PCIe network card? This will give you an MSI interrupt that won't conflict with any other devices in your system. I recall seeing some concerns with using MSI for real-time interrupts under Xenomai, but I believe it can be done successfully on x86 if you observe a few precautions (maybe Jan Kiszka can comment?). We've successfully used MSI for non-real time interrupts (ethernet cards) on many of our platforms. -Matt _______________________________________________ Xenomai mailing list [email protected] http://www.xenomai.org/mailman/listinfo/xenomai
