            Bug ID: 109297
           Summary: AMD RX 570: Hard reset when playing games
           Product: xorg
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/AMDgpu
          Assignee: xorg-driver-ati at lists.x.org

I have hard resets, similar to hitting the Reset-Button. Which means I get no
log or trace of any kind and I am totally clueless where/how to search.

I replaced a Geforce 770 with a MSI RX 570 in the hope of better support for a
multi-monitor setup. Turns aut the Card will expose the above issue when gaming
(so far played only X-Com2).

xserver-xorg-video-amdgpu is version 18.1.0,
kernel is  4.19.0-1-amd64 (had same issue with 4.18)

-   The PSU is a Seasonic Platinum 400 Fanless, more than enough to drive the
card and the max ~100W Cpu.
    I replaced a Geforce 770, which should have a higher peak without issues.

-   Xcom2 crashes after ~5 to 30minutes. I can play longer if I
    limit the card to 80 W.
    echo 80000000 > /sys/class/drm/card0/device/hwmon/hwmon2/power1_cap

-   The system does not cause any troubles with Windows 10,
    even if both CPU and GPU are tortured.

-   I did sample the temperature berofe the crash, it was below 70degrees GPU
and below 60 on GPU. (far from any BIOS triggers)
