/proc/interrupts "ERR"

On my eap615 I do "cat /proc/interrupts" and the last entry is

ERR: 14577

Is this a counter for wifi issues or what ? On my old AC1750 I see the same entry but the value is all way s 0 .

device on openwrt 22.03.5

ERR is incremented in the case of errors in the IO-APIC bus (the bus that connects the CPUs in a SMP system. This means that an error has been detected, the IO-APIC automatically retry the transmission, so it should not be a big problem, but you should read the SMP-FAQ.
