To dig this issue further, try disabling all Xenomai skins (CONFIG_XENO_SKIN_NATIVE, _RTDM, _POSIX), only keeping the real-time nucleus in. The klog should say after reboot: [ 2.371256] Xenomai: hal/x86_64 started. [ 2.371363] Xenomai: scheduling class idle registered. [ 2.371454] Xenomai: scheduling class rt registered. [ 2.373676] Xenomai: real-time nucleus v2.5-rc3 (Flying In A Blue Dream) loaded. without any further Xenomai message. If that still does not work, try disabling CONFIG_XENOMAI entirely, only keeping the interrupt pipeline active. This way we may better understand which software stack is causing issue. > _______________________________________________ > Xenomai-help mailing list > Xenomai-help@domain.hid > https://mail.gna.org/listinfo/xenomai-help -- Philippe.
