Simple diff/patch to test the issue
See attached diff/patch for what I am trying as a quickfix and testing what
causes the issue. Not a "real fix" just supposed to be used for TESTING!!!
My suspection is that the change in the "r600_buffer_common.c" file might be
needed for other cards too for setting the flag for the faster code path but it
maybe happens only for r600 because it is in this file?!
That is only my wild guess so far and will test this with the lot of logging in
the patch... Only provided for those who want to understand my later logs I
provide after building a version with this patch in place.
