You seem to have avoided the usual pitfalls, however you really have a lot of options enabled. The symptoms of your problem really look like a bug which I had and turned out to be a NO_HZ problem. So, maybe you could try and disable CONFIG_NO_HZ ? You can also try to enable Xenomai's NMI watchdog, which will fire if a timer overrun occur. -- Gilles.
