[Nouveau] [Bug 87819] [NVAC] EQ overflowing

Hello! I have the same issue, after restoring from memory suspend ("echo mem >
/sys/power/state")
(EE) [mi] EQ overflowing. Additional events will be discarded until existing
events are processed.

(EE)
(EE) [mi] These backtraces from mieqEnqueue may point to a culprit higher up
the stack.
(EE) [mi] mieq is *NOT* the cause. It is a victim.

Correct.

It's best to think of nvkm/ as a separate entity, and it will be at some
point (drm load on its own, inside a vm), and drm might not be able to
access it's internal structures.
That's not the case now, so the code is fine as-is for the moment. But it's
worth keeping in mind.
Thanks,
Ben.
