Commen= t # 14 on bug 97069<= /a> from Clemens Eisserer 
I was able to track the TTM issues down to a very small cohere=
nt dma memory
pool setting (4MB). With the kernel options "coherent_pool=3D128M cma=
=3D256M" 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.
