I had exactly the same problem.
Then it looked like 2 bugs. One was in mesa and the way it didn't upload
relocations for constant buffer, and other problem possible was in kernel, but
I am not very sure about that, and anyway you have new enough kernel not to
worry about.

So please make sure you have recent enough mesa (7.11 should be enough).

Also to reproduce that easily (cat /sys/kernel/debug/dri/0/evict_vram) was
added.
Just read that file few times like that:

cat /sys/kernel/debug/dri/0/evict_vram

(That assumes you have debugfs mounted on /sys/kernel/debug)
