            Bug ID: 102498
           Summary: Monitors blink every 10sec and layout resets after
                    returning from powersave or sleep
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu

dmesg

One or both monitors (ASUS much more often) continously blink once in 5-10
seconds. This happens only in linux and not in grub or windows. Second problem
is that monitor layout resets to mirrored from extended desktop when monitor
returns from powersaving to show lockscreen and I need to rerun xrandr. There
are some errors in dmesg, so it is attached. Log is from right after returning
from being AFK and giving lockscreen password. This bug is continuation to my
previous problem in Bug #102300.

You mentioned on bug 102300 that this is a recent linux-amd-staging regression.
Please mention the last known good and first known bad version.

It is not a reggression. I tried and it happens with older amd-staging kernel
from before I updated.

1) Monitor layout reseting when returning from sleep is an old problem, I'm
sure it's been at least from November 2016, maybe even earlier. At one point of
time it only happened sometimes (before Dec 2016), now always. 

2) Blinking only happens with linux-amd-staging kernel, not in stock.

I tested with latest Archlinux stock kernel 4.12.8-2 and it still keeps ASUS
black on boot, but unlike when I reported #102300 I can restore the picture by
switching to mirrored and back to extended desktop in XFCE (worked even after
few reboots). I can confirm there is no blinking with stock kernel.

Only difference to before in stock kernel is that ASUS 60.00 refresh seem to
work now. Difference to amd-staging kernel is that stock reports DVI-I-1 and
amd-staging DVI-D-1.

Fully updated Arch with stock kernel:

and from amd-staging
