Kernel message in log RT-AC86 - 386.1_beta5

[St561n]

Hi,

I am new to the asus/Merlin world and I hope that somebody can help me with the following question:
After installing diversion I get every about 20 minutes the following messages in the log file:

I tried already to search for some of the message but I was not able to find something specific.
Before I was able to install diversion I had to format the USB stick connected to USB3.0 port to ext4 which I did via putty. Somewhere around this the router rebooted (was may be also at the point where I switched from USB Mode 2.0 to 3.0. After the restart the router lost time/date and I was not able to start amtm until time was synchronized again. I mention this because it may have also an impact on the above mentioned messages.

Hope that some expert can help me.

Thank you very much in advance!
