<pre>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 at expected performance.
I'll give it a try next week to see whether this also fixes the issues with
GL_ARB_buffer_storage.</pre>
