Please describe the full sequence that leads to a hang. Was i915 […]
- Boot Linux without loading i915. - Run gfx_test without the workarounds. - After gfx_test exits and the machine enters a low-power state, it will lock up.
If something keeps the CPU from getting into low-power states (e.g. `cat /dev/zero > /dev/null`), the machine will not lock up. However, stopping the load task after gfx_test has run will result in a lock-up.
