That seems to imply that drm->fbcon->helper == NULL. But that's not what you're
seeing on recent kernels, so the implication is that there's some sort of
second concurrency bug in the rev you identified that got fixed later on.... I
don't think that your bisect results are valid as a result :(

Was the original problem 100% reproducible? If so, you should mark any kernel
that works sometimes as "good" (even if it's not really *that* good).

Also, the original problem is just monitors not working, but you can ssh
in/etc, right? Or does the system totally hang? (Doesn't seem that way given
that logs showed up in systemd...)
