Description (partial)

Symptom:
Linecards showing as "hw-faulty" in "show module" command after recovering from auto Linecard power Shutdown.

Conditions:
if Linecard power shutdown feature is enabled and if multiple linecards are power shutdown due to lack/loss of power then some linecards might show as "hw-faulty" upon recovering the power supply. This is false positive.

This behavior could also be observed with linecard OIR however occurrence if very rare. Almost negligible.
