- In some circumstances, the drm/i915 driver slept on irq_lock with no timeout and never woke up, causing the X server to become unresponsive
- It turns the absence of timeout came from the original FreeBSD version of this driver; Linux uses a 1 second timeout by default
- Add the same 1-second timeout to the culprit function calls, hopefully fixing this issue for good
