--- Comment #14 from Clemens Eisserer <linuxhippy at gmail.com> ---
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.
