I see kernel panic with kselftest merge configs on Juno-r2 and Rpi4.
Is there a way to reproduce this setup on Qemu?
Not reproducible on Qemu-arm64. I see only on arm64 devices Juno-r2 and Rpi4.
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?
Here is the link for rootfs - OE one. https://storage.tuxsuite.com/public/linaro/lkft/oebuilds/2RVA7dHPf73agY0gDJD...
I tested this rootfs and couldn't reproduce on Qemu. Now, I will try to use my raspberry pi and try to reproduce this.
Thanks.
Thanks, Puranjay
