Are you saying you can't reproduce it?
It *should* be complete yes. with kernel 5.7/5.8 it should oops when you
reboot.
I will admit though that I adjusted the reproducer a little bit in an
attempt to make it fit fedora.
So if it doesnt oops for you and if you use 5.7/5.8 then maybe the
reproducer got mangled in the conversion.
