            Bug ID: 105049
           Summary: Invalid usage of vulkan pipeline barriers can cause
                    amdgpu to deadlock
           Product: Mesa
           Version: 17.3
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Vulkan/radeon
          Assignee: mesa-dev at lists.freedesktop.org

  --> https://bugs.freedesktop.org/attachment.cgi?id=137278&action=edit
src code for my program + its CMakeLists.txt and the script I build it with

So I was messing around with my neat little vulkan program and managed to make
the amdgpu driver freeze. TTY consoles still work but if you enter an TTY with
xorg running you can't get out or do anything. Any new xorg servers you start
will stay frozen, ect. Audio still plays.

Expect:
My faulty program shoud've just crashed.

What Happened:
Nothing graphical responded.

Attached:

calltrace: A call trace from the kernel because the process was hung
glinfo: results from running `glinfo`
glxinfo: results from running `glxinfo`
logfromssh: what the program outputs when run from ssh with x-forwarding
(program crashes before it can lock the gpu)
pacaur: results from running `pacaur -Q | grep "vulkan\|mesa\|xf86"`
vulkaninfo: results from running `vulkaninfo`
debuginfo.7z: src code for my program + its CMakeLists.txt and the script I
build it with
