            Bug ID: 101685
           Summary: [amdgpu][tahiti xt] dota2 random crash
           Product: Mesa
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: blocker
          Priority: highest
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: sylvain.bertrand@gmail.com
        QA Contact: dri-devel@lists.freedesktop.org

steamos beta (debian), mesa 17.1.2, linux kernel 4.12
Dota2 randomly crashes: Jul 4 10:32:45 steamos kernel: [ 1728.851665] traps:
Globpool1[1352] general protection ip:7f6a0a2a149 sp:7f6a1e9ea790 error:0 in
libparticles.so[7f6a0a110000+579000]
If I run the game with the radeon linux module instead of the amdgpu linux
module, I don't get any crash, but the game runs _significantly_ slower.

I was wrong, it's worse: linux 4.12 amdgpu and radeon do random crash dota2 the
same way (in libparticles). Both 4.12 modules are _significantly_ faster than
the stable 4.11 radeon while not crashing.

Is this a regression?  If so, did you also change the mesa version you are
using?

Same mesa binaries from up-to-date "beta" steamos: 17.1.2.

As far as I tested it, I cannot even play one dota2 game without the game
program randomly crashing in dota2 libparticles (radeon or amdgpu).

Running dota2 vulkan with git mesa and git llvm now. The crash seems gone. I'll
play a bit and we will see.

Have been playing for days and hours to dota2-vulkan

No crash whatsoever, just significantly slower than gl rendering and what seem
rendering bugs.

closing.

So what I'm still missing is (1) was the original bug using GL or Vulkan? (2)
if GL in (1), does the issue still occur on GL?
