Are you patching the Xilinx Linux kernel with the Xenomai patch? Have
you tried mainline?

Linux 4.9.51 on Xilinx Zynq 7000 MPSOC
Hi Greg! I've read all your blog post on this argument! With the xilinz
linux kernel i have no problem!
Saluti,

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.
