For several weeks now, the wlan0 interface in our Turris Omnia (firmware version: OpenWrt omnia 15.05 r47055) locks up every couple of days (SSID disappears for clients) until I reboot the device. When this happens, the System Log shows repeatedly the following line:
2018-08-11 08:18:03 warning kernel[]: [639502.620955] ath10k_pci 0000:02:00.0: failed to send pdev bss chan info request
And the Kernel Log shows:

Any idea what might be causing this? Is this more likely a software or a hardware defect?
