New Intel G3258 CPU, new MSI board, same problem:
The GPU interrupt fired like crazy on monitor unplug.
lspci output:
00:02.0 VGA compatible controller: Intel Corporation Device 0402 (rev 06)
Subsystem: Micro-Star International Co., Ltd. Device 7817
Flags: bus master, fast devsel, latency 0, IRQ 11

Shouldn't we just add entries for them all? See include/drm/i915_pciids.h
We might need to abstract the macro magic a bit though to reuse that list.
Also note that not all have the DEIER register. In any case I don't think
this game of whack-a-mole here is, we should plug this all for real.

Dropping for now, please resend if necessary after resolving Daniel's
question.
