--- Comment #4 from Daniel Vetter <daniel at ffwll.ch> ---
How much time is "immediately" in your step 5? Is this while the system is
still resuming, or are a few seconds later on also still able to repro the bug?

For theories I have two ideas
- Disabling the irq also kills the DP hotplug detection logic.
- The interrupt storm logic isn't properly reset over a resume.

The combination of these might be enough to explain what's going on here ...

One more thing: Can you test patches and git trees on this machine?
