I think it's unlikely that my patch is causing the problem, because my patch is very simple and doesn't have any effect on the kernel. I don't know if there is something wrong.
I used the above config (make olddefconfig) to compile this commit, and it crashed directly after starting it in qemu.
Thanks.
