Possibly related problem on r300 code paths:


It took me a whole lot of time to analyse the source of the problem and this is
the commit that causes slowdown for me too.

For me it was really useful to do an strace before and after this commit and I
find the GEM_CREATE numbers rise from around 7-11 to about thousands when just
doing 10 seconds of glxgears which is clearly wrong and causes my slowdown.

Maybe would be useful to test if the problem is also related to GEM/TTL in this
case? Just informing you because I have found this earlier issue when googling
the commit hash...
