Looking at the "debugging X freeze" page.

The GPU itself does not seem stuck; VT swiches are possible, /sys/kernel/debug/dri/0/i915_error_state is clean, as is i915_wedged and the content of i915_ringbuffer_info keeps changing.

Option "AIGLX" "off" does not resolve.

Option "NoMTRR" "true" prevents the freeze.
