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
irq_mode 1 reset_mode 0
[  216.907165] ath10k_pci 0000:06:00.0: failed to receive initialized
event from target: b8600448
[  216.907166] ath10k_pci 0000:06:00.0: failed to wait for target after
cold reset: -110
[  216.907167] ath10k_pci 0000:06:00.0: failed to reset chip: -110
[  216.907220] ath10k_pci: probe of 0000:06:00.0 failed with error -110

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
