I wonder if the best fix would be indeed to deactivate irq coalescing
completely.
Does it make any sense at all to use it if a driver uses NAPI already?

It absolutely does make sense, when it is implemented and functions
properly.

Interesting. I always thought both (NAPI and irq coalescing) are essentially doing the same thing only
one time in software and one time with hw support. Did I misunderstand NAPI?
