Issue still happens despite kernel updates and mesa updates on=
openSUSE
Tumbleweed. Same happens on Kubuntu with oibaf ppa, and on Arch.
It seems this bug affects many people on linux using AMDGPUS, and found some
interesting workarounds. Had a look at kernel options, applied to grub, and=
so
far it has been 2 weeks of extensive testing, and I did not have a single
system freeze or hang.
-> BEGIN KENEL PARAMETERS <-
This is what I am using now. Please note that some of those settings are to
enable debugging and should not left there forever. I will remove those once
I am confident with the stability of the system.

- Kernel parameters explained from:
https://=
www.kernel.org/doc/html/latest/gpu/amdgpu.html
--- dc (int)
Disable/Enable Display Core driver for debugging (1 =3D enable, 0 =3D disab=
le).
The default is -1 (automatic for each asic).
--- dpm (int)
Override for dynamic power management setting (1 =3D enable, 0 =3D disable)=
. The
default is -1 (auto).
--- vm_update_mode (int)
Override VM update mode. VM updated by using CPU (0 =3D never, 1 =3D Graphi=
cs
only, 2 =3D Compute only, 3 =3D Both). The default is -1 (Only in large BAR=
(LB)
systems Compute VM tables will be updated by CPU, otherwise 0, never).
--- ppfeaturemask (uint)
Override power features enabled. See enum PP_FEATURE_MASK in
drivers/gpu/drm/amd/include/amd_shared.h. The default is the current set of
stable power features.
--- vm_fault_stop (int)
Stop on VM fault for debugging (0 =3D never, 1 =3D print first, 2 =3D alway=
s). The
default is 0 (No stop).
--- vm_debug (int)
Debug VM handling (0 =3D disabled, 1 =3D enabled). The default is 0 (Disabl=
ed).
-gpu_recovery (int)
Set to enable GPU recovery mechanism (1 =3D enable, 0 =3D disable). The def=
ault
is -1 (auto, disabled except SRIOV).
