If you load a non Xenomai kernel do you see the panic? I think there's an issue with your rootfs. I've tested zynq running on 4.14 ipipe and 4.9 ipipe with Xenomai 3.0.x stable using both a ubuntu and busybox file system with no issues. I've tested on Zybo, Minized and the Zc702 board. If it's a rootfs problem and not Xenomai related I can help you off list. Try loading a non Xenomai kernel and see if the panic still exists.
