           Summary: GPU lockup in Team Fortress 2
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: Enrico_m@gmx.de


After updating mesa to current git I always get a GPU lockup when the game is
about to start. After git bisect I got the following commit:

    prog_optimize: Fix reallocating registers for shaders with loops

    Registers that are used inside of loops need to be considered live
    starting with the first instruction of the outermost loop.

    NOTE: This is a candidate for the 7.9 and 7.10 branches.
