Line number information for the backtrace, since I compiled the driver on a
different system:
0x432f7 is in kgem_create_2d (kgem.c:5809).
5804 bo->delta = 0;
5805 DBG((" 1:from active: pitch=%d,
tiling=%d, handle=%d, id=%d\n",
5806 bo->pitch, bo->tiling, bo->handle,
bo->unique_id));
5807
assert(bo->pitch*kgem_aligned_height(kgem, height, bo->tiling) <=
kgem_bo_size(bo));
5808 assert_tiling(kgem, bo);
