I suspect you are running out of CPU accessible vram depending on your
configuration. There are patches for mesa and the kernel to allow the
use of non-CPU accessible vram for display buffers in kernel 3.17 and
mesa git so you might try a newer kernel and mesa.
The kernel changes for that will only be in 3.18, right?
