My workstation running arch linux with a RX560 GPU randomly reboots after a few minutes of use with the new amdgpu version in kernel 4.15. It seems to mostly happen when there's a full screen redraw happening (such as maximizing a window.) It happens regardless of desktop environment (I've tested GNOME on both wayland and Xorg, as well as KDE). If it's left at the GDM login screen it doesn't seem to reboot.
Kernel version 4.14 and older seems to be rock solid.
I've tried the following things to workaround it but nothing seems to make any difference:
- Setting amdgpu.dc to both 1 and 0
* Disabling dpm by setting amdgpu.dpm to 0
* Upgrading MESA from 17.3.2 to latest git master
