I've hit this in the past but need to go and look up what this was. I am seeing it again on the 8822C but not on my others currently after updating the driver. [979.253737] rtw881: [TXGAPK] unknown channel 234!! [979.260576] rtw881: failed to send h2c command [979.684546] rtw881: failed to poll iqk status bit [979.876891] rtw881: failed to do dpk calibration [980.068887] rtw881: failed to do dpk calibration (private note: hope there's no global involved given I attach <n> rtw88 devices to the same system)
