GALLIUM_DDEBUG: folder ddebug_dumps with multiple dumps
OpenGL renderer string: AMD RAVEN (DRM 3.23.0 / 4.16.0-2.fc27.x86_64, LLVM
6.0.0)
My system is an Acer SF315-41 (Ryzen Mobile 5 2500U) with Fedora 27, Kernel
4.16-drm-next (based on 4.15-rc8), LLVM 6.0.0-rc1, Mesa 18.0.0-rc2.
I can reproduce these crashes from kernel-4.15-rcX/mesa-17.3/llvm5 to
kernel-4.16-drm-next/mesa-18-rc2/llvm6-rc1 and in between. They mostly appe=
ar
while watching videos (firefox/totem), switching tabs in firefox, resizing
windows (gnome-shell) or gaming.
With amdgpu.lockup_timeout=3D2000 and amdgpu.GALLIUM_DDEBUG=3D2000 I was ab=
le to
gather lots of dumps within a few minutes (see attachment). As you can see =
in
the dumps the GPU lockup results sometimes in a CPU lockup (kernel bluetooth
deadlock) as a result of gnome shell=E2=80=99s complete freezing. I can rep=
roduce
amdgpu crashes also with an USB mouse and bluetooth disabled.
Not very often I can find some kernel errors in the logfiles that result fr=
om a
crash. I=E2=80=99ll attach the few I found in the last two weeks.
