@Christopher: I still have this crash with the upstream kernel version 3.12.0-031200.
It seems that it still crash in 'r600_pcie_gart_tlb_flush'.

Note that I no longer have this crash if I remove this line from /etc/init/lightdm.conf (please have a look to the comment #7 for more details about that):

    echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

But then, my ATI/AMD GPU is still enabled and consume a lot of resources...
