Description of problem:

Details and attachments are reported in: 


Version-Release number of selected component (if applicable): I have tried with mesa stock version from fedora 17.1.5, kernel 4.12.4-300.fc26.x86_64) and also with che/mesa git version 17.3

How reproducible:

Use some POLARIS12 AMD card and will got random screen freeze, or use glmark2 and will get the freeze at:

Additional info:

Using var:


for glmark2 is working as workaround

using var 
MESA_GL_VERSION_OVERRIDE=2.1 in /etc/environment also works as workaround for gnome session (I got random screen freezes also playing videos or on some logins).

Comment 1 Pablo Estigarribia 2017-08-25 02:43:48 UTC
On latest test th glmark2 passed but changing dpm from auto to high with: 

echo "high" > /sys/class/drm/card0/device/power_dpm_force_performance_level

as root.

Comment 2 Pablo Estigarribia 2017-08-25 02:48:19 UTC
also tested game Insurgency that had same problem as glmark2 and it works now! 

seems that dpm is buggy on this radeon card, probably is better to disable it by default or put it on high performance for a more stable usage for users. 

https://www.x.org/wiki/RadeonFeature/#note_15 say:

"high" forces the gpu to be in the "high" power state all the time. The "low" power state is selected when the monitors are in the dpms off state. The "profile" method is not as agressive as "dynpm," but is currently much more stable and flicker free and works with multiple heads active.

Comment 3 Pablo Estigarribia 2017-08-27 13:04:27 UTC
Everything works fine disabling dpm on amdgpu. 

Workaround steps: 

edit /etc/default/grub

add amdgpu.dpm=0 to GRUB_CMDLINE_LINUX=

generate new config: 

sudo grub2-mkconfig -o /boot/grub2/grub.cfg

reboot (to test new permanent config is done. 

You will notice now /sys/class/drm/card0/device/power_dpm_force_performance_level doesn't exist. 

For months I though the problem was somewhere else, and was looking for many combinations without success, without this workaround I had a very annoying experience working, playing videos, whatever, because randomly I had freezed display and had to restart. I couldn't play any game before, now tested with many games and everything is perfect. 

Could be good to apply this workaround by default? so users doesn't experience the annoying bug?

Comment 4 Pablo Estigarribia 2017-09-12 10:39:17 UTC
latest update sent in https://bodhi.fedoraproject.org/updates/FEDORA-2017-2873fa1fb6, still doesn't fix this bug. 

good workaround could be to put default performance in high for all users? until getting the bug definitively fixed?

Comment 5 Pablo Estigarribia 2017-09-12 23:14:04 UTC
Got better workaround while waiting to have this permanently fixed:

1) download radcard script: 


2) chmod +x radcard

3) sudo cp radcard /usr/local/bin/radcard

4) Create systemd unit to change value at logon, unit file: 

sudo gedit /etc/systemd/system/amdgpu-dpm.service

    Description=Change dpm to performance high

    ExecStart=/usr/local/bin/radcard set high
    ExecStop=/usr/local/bin/radcard set bal


5) Start and see status

sudo systemctl start amdgpu-dpm.service
sudo systemctl status amdgpu-dpm.service

Should see something like:

[root@192 ~]# systemctl status amdgpu-dpm.service 
● amdgpu-dpm.service - Change dpm to performance high

sep 12 20:08:08 localhost.localdomain systemd[1]: Started Change dpm to perform

6) Enable this

sudo systemctl start amdgpu-dpm.service


You can change the commands to your better choices.

Comment 6 Pablo Estigarribia 2017-10-11 13:21:33 UTC
I have noticed that the "oneshot" unit in systemd execs both : start/stop script, so to have it always high I had to change this: 

4) Create systemd unit to change value at logon, unit file: 

sudo gedit /etc/systemd/system/amdgpu-dpm.service

    Description=Change dpm to performance high

    ExecStart=/usr/local/bin/radcard set high
    ExecStop=/usr/local/bin/radcard set high


Comment 7 Chris Siebenmann 2018-02-23 15:42:36 UTC
I have experienced this hang or something similar enough to it that it
was mitigated by setting 'amdgpu.dpm=0' on the kernel command line. My
environment is Fedora 27, a Gigabyte Radeon RX 550 card, AMD Ryzen 1800X,
Asus Prime X370-Pro motherboard, and Kingston ECC RAM.

(This happened in early January, which is a few Fedora 27 kernels ago.
I haven't tried to reproduce in the latest ones because my interest in
having my primary machine lock up on me is low.)

FYI: your amdgpu-dpm.service ExecStart isn't working the way you expected
because you also need 'RemainAfterExit=True'. Without it, systemd thinks
that your script has failed/stopped after the script exits, so it runs
your ExecStop script.

Comment 8 Chris Siebenmann 2018-04-04 17:19:22 UTC
With all of the current updates applied, my system no longer appears to
lock up this way and the 'amdgpu.dpm=0' kernel command line parameter is
unnecessary. Various package versions:


(and possibly other relevant packages, but I don't know.)

Comment 9 Pablo Estigarribia 2018-04-05 22:44:40 UTC
You are right Chris, 

I have removed the customizations on my system and found the bug is not there, same with live cd.

What I see:

Someone disabled dpm by default, probably upstream? because I haven't see any comment about it on some other places.

After boot without customizations:

$ cat /sys/module/amdgpu/parameters/dpm

$ cat /etc/default/grub 
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora/root rd.lvm.lv=fedora/swap rhgb quiet"

Comment 10 Tim Cuthbertson 2018-04-06 00:14:51 UTC
My HP notebook system running Fedora 28 Beta (fully updated) still has this problem.

CPU: 3 PID: 800 Comm: systemd-logind Not tainted 4.16.0-300.fc28.x86_64 #1
Hardware name: HP HP ProBook 450 G3/8101, BIOS N78 Ver. 01.24 01/29/2018

amdgpu.dpm=0 does resolve it.

Is the upstream bug the one at freedesktop #101976?

Comment 11 Pablo Estigarribia 2018-04-06 01:51:44 UTC
Ok, what's the status of dpm by default for your system?

I have reported that in freedesktop yes, I have forgot it as no response and no comment from anyone there.

Comment 12 Pablo Estigarribia 2018-04-06 01:56:49 UTC
What I see is: this could be "resolved" if dpm is disabled for amdgpu, and looks as critical as normal users will never understand why their systems freezes on a default install.

Looks like someone changed it for Polaris 550 or not? 

@tim which one is your graphics card?

In this link http://www8.hp.com/us/en/products/laptops/product-detail.html?oid=7834555#!tab=specs I see only intel graphics.... 

Probably new bug report is required to address the bug on that one.

Comment 13 Chris Siebenmann 2018-04-06 19:08:41 UTC
On my hardware (Gigabyte Radeon RX 550), amdgpu.dpm=0 had clear effects on at least power usage; it appears to have restricted my card to a very low power mode, more or less its minimum power usage (and well under basic power usage in X normally). It also caused fan and temperature reporting to stop being visible in lm_sensors output (normally both show up as an 'amdgpu-pci-0900' sensor). I suspect that this power restriction caused lower graphics performance, but I don't have figures on that (and I don't have the interest to re-restrict my machine to make measurements).

All of this suggests that it would be undesirable to set amdgpu.dpm=0 by default. It seems clearly better to have AMDGPU DPM enabled on setups that can use it without locking up.

Comment 14 Pablo Estigarribia 2018-04-06 19:33:48 UTC

What you are finding here looks good arguments to keep it open.

You can also enable dpm and change performance always to high (look comments above), it works for me.

Comment 15 Tim Cuthbertson 2018-04-07 15:31:04 UTC
My discrete card is a Topaz XT Radeon R7 M340. I am not sure what the default dpm setting is - How do I determine that?

My system does not even use the discrete card by default, but it makes it crash with a kernel oops, anyway. The default onboard graphics is Intel HD 520.

The oops is Apr 05 07:09:28 tim-fedora-hp kernel: Oops: 0002 [#1] SMP PTI

My kernel is 4.16.0-300.fc28.x86_64

Comment 16 Marc Ranolfi 2018-04-14 00:15:31 UTC
I'm affected by this.

For months now I've been running with DPM set to "Low" using an udev rule, as a temporary workaround. I set it to "high" when I want to game, which is a rare event these days.

My solution is available at https://gitlab.com/snippets/1709853 and https://gitlab.com/snippets/1709854.

I can't reproduce what Chris Siebenmann described - i.e. in my system lm_sensors output is correct with either DPM state - but I definitely agree that DPM should be working and in use if the card supports it, no question about it.

Bug is present in kernel 4.15.10. I'm going to test with kernel 4.15.15 later.

Comment 17 Pablo Estigarribia 2018-04-14 01:00:25 UTC
After looking again into the files of the card0, I have noticed that dpm is enabled by default! (I have been confused because the file changed its place).

Now it is here:

cat /sys/class/drm/card0/power/control 

uname -a
Linux powers11 4.16.1-300.fc28.x86_64 #1 SMP Mon Apr 9 15:29:05 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Also their outpus have same files:

card0-DP-1/     card0-HDMI-A-1/ device/         subsystem/
card0-DVI-D-1/  dev             power/          uevent

So it is really fixed for fedora 28!! (kernel 4.16.x)

I have been using this for weeks and not noticed this bug!

Also tested glmark2 and some game just to see if something crashes.

Comment 18 Marc Ranolfi 2018-04-14 05:59:23 UTC
Strange. I'm now running kernel 4.16.2 as we speak and the bug is still present.

Even though I had seen some interesting commits to mainline kernel regarding DPM under '/drivers/gpu/drm/amd/amdgpu/'.

P.S. Can still read lm_sensors GPU temperature with the performance level fixed to either "low" or "high".

I've publish a new version to https://gitlab.com/marc2377/rforcedpm which also handles the <auto> state.

Comment 19 Pablo Estigarribia 2018-05-18 02:59:53 UTC
Today reinstalled fedora 28 and did an upgrade.

Got 3 times the 'blank' screen just working on gnome session, same behaviour as before. 

So looks like this bug is still open.

Comment 20 Marc Ranolfi 2018-05-18 04:20:10 UTC
Of course it is; I'm now on kernel 4.16.8 and still affected.

Comment 21 Pablo Estigarribia 2018-08-17 23:43:14 UTC
Looks good for me on kernel 4.17 on fedora with mesa 18 now.
Fedora 28 with all updates, will close as it has been many weeks without issues.

If something appears to be wrong again, will reopen it.
