CPU Pinned not visible in IRQ after pod restart

Solution Verified - Updated -

Issue

Pods that are meant to be isolated from IRQs sometimes still have some IRQ scheduled on their CPUs.
The irqbalance file /etc/sysconfig/irqbalance and /proc/irq/default_smp_affinity are not reflecting values that match the pods assigned CPUs.
