Sorry for missing your report here. Before we disable this again for gen4 I want to make sure that it's the same irq misrouting issue which was already the cause for the gmbus irq mess. Can you please boot with pci=nomsi (so that i915 uses irq16)?

If that's confirmed then I think we should add the same comment we've added in intel_i2c.c to this code so that no one dares to wake this dragon again. I'll do that when I commit the fix.

Confirmed, with MSI disabled, i915 is using IRQ 16 and everything is working well.
