Ok, to draw things together again: I originally submitted Bug #1153587, where you identified the missing TLB invalidate as the reason and suggested that an upgrade to kernel v3.8 would fix it. I installed Kernel v3.8.2 but the problems continued. You asked to provide /sys/kernel/debug/dri/0/i915_error_state, which I was not able to provide, so instead I submitted this bug report here, hoping that the relevant information would be added automatically. Based on the current crash report you again identified the missing TLB invalidate as the reason and claim that Kernel v3.8 would fix it. In your last comment about Bug #1153587, you mentioned that something might be wrong with rc6. Would deactivating rc6 be a way to break out of this loop? How can I do this?
