OK. (I'm using 4.15.0-51-generic from ubuntu).

Could you run with QEMU under gdb, and when it hits the
assertion go back up a stack frame to the arm_cpu_realizefn()
frame, and then "print /x cpu->isar" ? That should show us
what we think we've got as ID registers from the kernel.
(You might need to build QEMU with --enable-debug to get
useful enough debug info to do that, not sure.)
