The first one resulted in "timed out to flush queue 3" messages from the driver and sometimes a complete stall of the TX queues. The second one is specific to the RTW8821CU chipset. Here 2GHz networks were hardly seen and impossible to connect to. This goes down to misinterpreting the rfe_option field in the efuse.
