            Bug ID: 104817
           Summary: [Raven][GALLIUM_DDEBUG] system crashes/freezes
                    randomly every few minutes/hours
           Product: Mesa
           Version: git
          Hardware: All
                OS: Linux (All)
            Status: NEW

          Priority: medium

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 appear
while watching videos (firefox/totem), switching tabs in firefox, resizing
windows (gnome-shell) or gaming.

With amdgpu.lockup_timeout=2000 and amdgpu.GALLIUM_DDEBUG=2000 I was able 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’s complete freezing. I can reproduce
amdgpu crashes also with an USB mouse and bluetooth disabled.

Not very often I can find some kernel errors in the logfiles that result from a
crash. I’ll attach the few I found in the last two weeks.

I am also having this problem. Ryzen 2500u on kernel 4.16-DRM-next. Many hangs
that require a reboot to fix.

Although it also seems very likely that this is a Kernel driver issue.

OP also filed a kernel bug about this. It missed the crucial information about
how he was able to debug it! Glad I found this one.

It seems to me that this is in fact a CPU related problem. Since July 25 I
don’t have any problems. My system is pretty stable. What helped was to add
idle=nomwait to my GRUB command line. This has fixed those problems for me.

Please try to add idle=nomwait to your GRUB command line. I think this bug can
be closed.

I added idle=nomwait recently and that has fixed it for me too. I thought I had
already tried this, not sure, but perhaps there were two issues and the other
has since been fixed.

See comment #8. Kernel parameter idle=nomwait fixed this bug for me. It seems
to be a CPU related problem.
