Hello, I misread the top information and "sirq" are at more than 50% with some traffic going through.
Actually, there are a lot of ERR interrupts reported in /proc/interrupts even just after booting the device: https://dev.openwrt.org/ticket/10037 How to check if both are related, and related to the ag71xx driver mentionned in the kernel oops ("<ag71xx_poll+1dc/58c>") ?
