Warning message

Hi.

I've found the following text in my openWRT system log (latest build on Netgear WNR2200):

What is it? Should I be worried about it?

I ask because sometimes my wifi connection becomes very slow, useless, but ONLY when I connect to it a raspberry pi 4 device in which openmediavault is installed (+external USB disk for NAS).
When the raspberry pi 4 is down, the openWRT router has no issues at all....

Thanks

This is a bug, something inside the kernel is failing hard, I would report it.

Thanks!
This is my first openWRT firmware after my long time using dd-wrt.
I see that the openWRT community is alive and willing to help. Great!
