Hi,
how do you do bisect ?build all kernel commit one by one ?
as you did before:
https://bugzilla.redhat.com/show_bug.cgi?id=1520982

what kernel source code do you use that occur warning at device_add_disk?
from fedora or any official release ? if so ,could you provide web link?

if you use same kernel source code and same .config, why your own build
Cann't trigger that warning ?
