Hello Pello,

Nothing is stuck QEMU is running and trying to boot your images.
Unfortunately we don't have all of the support in mainline QEMU to
boot the Xilinx kernel for the ZCU102 and the kernel is panicking.

You will need to use the Xilinx fork of QEMU. You can do this by
setting 'XILINX_QEMU = "1'"' in your locall.conf (you will need to
delete your tmp and rebuild after that).

Then you should be able to boot your images on QEMU.

Thanks,

Alistair
