Do you happen to know which models exacly have it? I'm trying to find a
reasonably priced laptop with QCA6390 from Finland or EU, no luck yet.
Apparently there was a certain Dell XPS 15 9500 model but it was almost
4k EUR.

I had the same problem as well back in the days, for me enabling
CONFIG_IRQ_REMAP helped. If it helps for you also I wonder if we should
mention that in the ath11k warning above :)
