   I actually see this after booting as well:
   ```

   ```
   Yes, I have enabled DEBUG_WIRELESS_INFO. This is on the RAMLOG (you can see I'm invoking dmesg).
   My guess is that there's unprotected concurrent access to syslog. Could syslog be called from "outside OS" within closed drivers?
   I couldn't find where this "I" or "W" is in the code.
