On a old kernel (3.8.13) after rebuilding to latest 3.8.13 to solve emmc issue (inability to flash) I am noticing more activity in log file (messages) with regard to usb wifi adapter (8821cu) which was built against 3.8.13.
Logs are added about every 20 minutes and they don’t appear to be warnings or issues - note driver is built with debug log set to error level and wlan0 connection is established with IP assigned.
Any suggestions on how to determine what level of these logs are and/or how to suppress?
