--- Comment #12 from o.freyermuth at googlemail.com ---
Tried with latest drm-tip as of fb7048acaac8ece5ebc53f9b748b76cdcef60fa3 using
the same kernel configuration I used with 4.16.3 (after running make
oldconfig).
I end up with a blank, but lighted screen *immediately* after the bootloader.
Neither sysrq nor any other keypresses apart from turning the machine hard off
are working.
No stacktraces found in pstore.
Other ideas?
