Description Kertesz Laszlo 2018-04-30 04:51:49 UTC
I have a Ryzen 3 2200g CPU on a Gigabyte AB350M-HD3 mobo. I have 2 monitors connected (same model), one via HDMI, the other via DVI.

OS: Debian Testing, kernel compiled from mainline git (rc2+ now, after the rc3 DRM fixes patches merge). But this issue is present even with the kernel from 
https://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-4.18-wip

The issue i encounter is the when the monitors enter dpms and tries to wake, the system freezes. 

This is not happening always, but it can be reproduced reliably with running 
"DISPLAY=:0 xset dpms force off"
Repeatedly. It will eventually lock up (minimum tries was 1, max 9).
One of the monitors (HDMI) will have the signal still cut, the other (DVI) will have a blank signal (this behavior seems consistent).

The system freezes totally (no ssh access, ping, magic keys etc). Also no usable logs. This is compounded by the issue of having to reboot repeatedly after this issue since the system will freeze at reboot when the KMS mode is enabled.

Maybe unrelated but i have this line in dmesg after each boot:

[    5.312547] [drm:construct [amdgpu]] *ERROR* construct: Invalid Connector ObjectID from Adapter Service for connector index:2! type 0 expected 3

xrandr output:

Please attach the dmesg output, captured as late as possible.

Not sure, when this happens to me the box is dead (no ssh etc).
Later i will try to dump "dmesg -wH" from a ssh session. I installed the dbg package and enabled the dc verbose logging option.

dmesg
Comment 5 Kertesz Laszlo 2018-04-30 19:52:05 UTC
Tried it and there is absolutely no relevant output in dmesg.
After freeze i had to force-restart the computer 5 times to pass the amdgpu loading point.
Attached dmesg above.
Comment 6 Kertesz Laszlo 2018-06-01 18:52:43 UTC
I did some additional testing and it seems that if i disable the monitor connected through DVI (xrandr --output DVI-D-0 --off), the HDMI monitor has no issues with dpms.
Comment 7 Kertesz Laszlo 2018-06-01 19:02:51 UTC
Tested with the DVI monitor only (disabled the HDMI) too and seems to work fine aswell.

I also tested with both and even now with kernel 4.17.0-rc7+ it locks up.
