I was able to track the TTM issues down to a very small coherent dma memory
pool setting (4MB). With the kernel options "coherent_pool=128M cma=256M" all
the code stressing texture up-/download works fine

ok, there seem to be problems with TTM or DRM - running the same benchmark on
nouveau also leads to an abort caused by issues with buffer allocation:
