--- Comment #1 from Michel Dänzer <michel@daenzer.net> ---
Sounds like a GPU hang, which is most likely caused by Mesa or LLVM. With the
environment variable GALLIUM_DDEBUG="pipelined 2000" set for the compositor or
Xorg process, the radeonsi driver might detect the hang and dump some
information about it in a file in ~/ddebug_dumps/ . Please attach that file
here.

The failure to recover cleanly from the problem is a kernel issue. You can try
setting amdgpu.lockup_timeout=2000 to make the amdgpu driver detect the hang
and try to reset the GPU, but it doesn't work reliably in general yet.

@Michel: How and where do I set the environment variable
GALLIUM_DDEBUG="pipelined 2000" such that it is passed to the execution
environment of the Xorg process or compositor? I use systemd as my init system
and the active service file is sddm.service. Presumably, I need to modify some
unit files but offhand I do not have an idea which one.

I could obtain the requested dump :) I hope it helps.

Some words are in order: After I knew that the guilty process was /usr/bin/X
and a knew its PID I also tried to get a "gcore <PID>" or to attach gdb to it.
Both failed. Otherwise I also had provided you a backtrace of all threads as I
compiled all packages with "-g -ggdb". (I am a gentoo user.) The process is
stuck in state "D". "kill -KILL <PID>" did not work either.

A second note (I know it is selfish, because you do a great job, and
off-topic.). I bought this new graphics card, because I was being pestered by
with an Nvidia graphics card, a buggy nouveau driver and a lot of crashes due
to an unstable OpenGL. (I know it Nvidia is to blame for the situation not the
maintainers of nouveau.) After 18 month of hope that the situation might
improve, I finally decided to spend money for a new graphics card by AMD. I
thought I would eventually get working PC. Now, it seems I stepped "out of the
frying pan into the fire". Just now I have still the chance to withdraw from my
investment and give the AMD graphics card back to the dealer. Should I do that?
Or may I hope for a fix soon?

Is there anything I can do to push this one forward? There are some events that
trigger the crash with high probability:
- autocompletion of URL in Firefox
- open context menu in Libre Writer
- scrolling source code in PhpStorm
Unfortunately, with this bug my PC is nearly unusable for daily work.

Anybody working on this? Anything I can help to push this one forward?

I still see this error and I can nearly reliably trigger it.

Notice that my bug report https://bugs.freedesktop.org/show_bug.cgi?id=102322
might be about the same symptom - but using a different GPU architecture, a
bleeding-edge new kernel, and I wanted to report this on the "amdgpu" driver
(not Mesa), because amdgpu produces the only logged error messages, and if the
bug was in Mesa that would not explain why my system totally crashes (and not
just X11).
