This indicates execution of AARCH64_BREAK_FAULT.
I see kernel panic with kselftest merge configs on Juno-r2 and Rpi4.
Is there a way to reproduce this setup on Qemu?
I am able to build the linux-next kernel with the config given below. But the bug doesn't reproduce in Qemu with debian rootfs.
I guess I would need the Rootfs that is being used here to reproduce it. Can you point me to the rootfs for this?
Thanks, Puranjay
