           Summary: r600g fails shader, tries to run with failed shader,
                    freezes.
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx
        ReportedBy: equinox-freedesktopbugs@xxxxxxxxxx


when trying to create a character in EVE Online, after the first few screens I
encounter multiple shaders that cannot be translated from TGSI. The error
message printed is:
"r600_pipe_shader_create - translation from TGSI failed !"

I've traced this down to:
^ check_and_set_bank_swizzle (-1) from
^ r600_bc_add_alu_type from
^ r600_shader_from_tgsi from
^ r600_pipe_shader_create (opcode: 0x09 "ADD")


Problematically, the application continues running after that, complains about
"missing shader" and finally - a whole few seconds later, continuing to draw
the loading animation - freezes the GFX card:

[ 4996.188064] radeon 0000:03:00.0: GPU lockup CP stall for more than 10000msec
[ 4996.188072] ------------[ cut here ]------------
[ 4996.188147] WARNING: at drivers/gpu/drm/radeon/radeon_fence.c:246
radeon_fence_wait+0x21c/0x2bb [radeon]()
[ 4996.188160] GPU lockup (waiting for 0x00011BDD last fence id 0x00011BD9)

after that I have to kill my X server and restart it.

(So this is basically two bugs, the shader failing, and the driver trying to
use a failed shader I assume - though the lockup might also be unrelated)
