Been following this thread for a while now as I just got 3 4k =
60Hz monitors
connected to the 3 DP ports on my Radeon VII.=20
I'm getting the exact same errors discussed in this report with matching dm=
esg
outputs.
I've applied the patches to Fedora 31's 5.3.0-3 kernel and everything now w=
orks
perfectly!
Just a few notes:
* Idle power draw before patch was 22W in lm_sensors, now it's reading 28W,
makes sense as the memory is now properly clocked. This also loosely matches
@Tom B's results.
* I did not get the repeated `[drm] schedsdma0 is not ready, skipping` in
dmesg, however, it is still possible to trigger a freeze by toggling dpms:
xset dpms force off
Resulting in:

Previously, without the patch, the machine hangs. With the patch, the displ=
ay
freezes for a few seconds and then power off. Mouse movement correctly turn=
s on
all screen and everything is back to normal.
