Description (partial)

A hardware interrupt causes service outage and a micro-code core will be generated. This condition puts the router in an inoperable state.

This issue would affect bundle interfaces such as MLPPP and GEC aggregate mode.

While processing dynamic reconfiguration events, one of the scheduling node is left in a committed but not forward state. When a flush packet is injected in a flush queue to complete the reconfiguration process, it causes a hardware interrupt when it traverses the node that was left in a non-forwarding state.
