The only difference with your .config file is that I have earlyprintk enabled but that should not cause the issue you are observing. I am using the raspbian rootfs downloaded from the raspberry pi foundation website: https://www.raspberrypi.org/downloads/raspbian/ can you try disabling xenomai from the kernel config to see if the problem happens also when only the IPIPE patch is turned ON?
