Xiaomi Mi Router 3G with MediaTek MT7621
I've tested with about 5 daily snapshots, but the problem still exists. I think snapshots based on kernels prior to 4.14.50 had no such problem as I had uptime more than 2 weeks
Router stops eth device until reboot, sometimes rebooted with this error automatically, but in most cases I have to login and reboot it manually.
Once I found a correlation with a device performing backup of WatsApp mobile application, router stops eth device in about 2 minutes after restart and return to normal working behavior only after finishing backup by this device.
Here is the messages from the log:

I've tested the patch provided by Felix Fietkau. It works fine on my Xiaomi 3G router.
I have 2 routers and both are more than 4 days uptime already with the firmware patched with the patch attached.
