Symptom
When you attempts to reload the switch with reload command, it freezes immediately and no logs are being presented or anything happens. Switch reboots only when a power cycle has been done.
Conditions
After reload command it`s entered switch is unresponsive and it doesn`t matter if you are connected through console cable or via SSH/Telnet. After 30-40 minutes switch reloads with printing the following error logs
%IOSXE-3-PLATFORM: R0/0: kernel: INFO: rcu_sched self-detected stall on CPU

Workaround
When we disable the IOX (no iox) issue is not present. Also if you are mirroring smaller count than 10000 pps it`s not observed.
Further Problem Description
The essence of the problem is coming from the traffic rate and the capacity of the traffic that it`s being mirrored.
