      I'm running in to a problem in Raspberry Pi 3 B+ running Kali Linux where WiFi controller freezes while in monitor mode, with the following error code under dmesg:

       

      brcmfmac: brcmf_sdio_hostmail: Unknown mailbox data content: 0x40012

       

      There are many people running in to this problem (based on the discussion thread below) but couldn't see any fixes from Cypress team. Can you please help?
