            Bug ID: 107150
           Summary: GPU restarts when some games are launched
           Product: Mesa
           Version: 18.0
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
          Assignee: dri-devel at lists.freedesktop.org

When launching some games such as Dirt Showdown, Dirt 2 (wine), War Thunder
(native), a cyclic restart of graphics occurs. During the launch of the Dirt
Showdown game, a black screen appears, then the display turns off and the phone
turns on, the game sounds. Then it repeats many times and then the system
hangs. It helps only the power off. It is also observed with other listed
games.
I ran games with the variable R600_DEBUG = nosb it helped only with War Thunder
(native), with others not.I remember that with mesa 17.x.3, Dirt Showdown was
launched exactly. The problem would not be so important if I had to register at
startup R600_DEBUG = nosb, but it is not. I would like that this error was
detected and did not interfere launch of similar applications.In advance thanks
to those who will respond to help in solving the problem.
