For some reason I don't see Nicola's reply in the list, I'll copy it
below just in case. So it looks like WLAN.RM.4.4.1 has a regression.

Hi Kalle, thanks for replying. This is the output of 'dmesg | grep
ath10k' when using the firmware file that works:

1448:[    3.485923] ath10k_pci 0000:3b:00.0: enabling device (0000 -> 0002)

And this is when using the faulty firmware file:
