After some times my banana r3 crashes with this kernel logs:

Please help me to understand the problem, and is it possible to have long time working for banana r3.

Please surround the log with three `

Which image do you use?

Yes, of course, I use OpenWrt 23.05.2. And it happened with my setup of programs (adguardhome, pbr, wireguard, zerotier…), but I think this is not the reason. This is about kernel working…
