Still the same issue :

[  213.889825] ath10k_pci 0000:06:00.0: limiting irq mode to: 1
[  213.889833] ath10k_pci 0000:06:00.0: pci irq legacy interrupts 0

upon those instructions :
https://github.com/kvalo/ath10k-firmware/pull/2
copying firmware-4.bin to firmware-5.bin seems to help for some users
