Ath10k_pci causes hardware restart

I'm using a HH5A which has two interfaces: ath10k_pci (which I use for AC) and ath9k (which I use for legacy). I just noticed that my router uptime is usually a maximum of 2 days so I started investigating. It seems that it restarts randomly because of these errors:

Mar 2, 2021 @ 08:49:34.033ath10k_pci 0000:02:00.0: failed to send pdev bss chan info request: -11
Mar 2, 2021 @ 08:49:34.033ath10k_pci 0000:02:00.0: wmi command 36977 timeout, restarting hardware	
Mar 2, 2021 @ 08:49:30.955ath10k_pci 0000:02:00.0: wmi command 36954 timeout, restarting hardware

Is there anything I can do to stop these restarts from happening? i.e. except for not using the interface.

This is my firmware version:

# ethtool -i wlan0
driver: ath10k_pci
version: 4.14.221
firmware-version: 10.1-ct-8x-__fW-022-538f0906
expansion-rom-version: 
bus-info: 0000:02:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no

also the kernel logs when loading the driver:
