Commen= t # 4 on bug 10572= 5 from hjpriester@= ;gmail.com 
Harry,

I have build a kernel using the:

    git clone -b drm-next-4.17-wip git://people.freedesktop.org/~agd5f/linux

I did the clone about 2018-29-03 20:00 UTC=20=20

The warnings are still there.
root@hjp2:~# dmesg | grep -i Warning

valid Length but zero Address: 0x0000000000000000/0x1 (20180105/tbfadt-658)

I never get the hang during a boot. I will report that as a separate bug.

The display I am using is a IIYama Prolite XUB2792QSU using Displayport.
It it a 27" 2560x1440 monitor.
The distrubution is Slackware-current. ("pre 15.0")
