Description (partial)

Symptom:
In some conditions a blade using M81KR (VIC/Palo) adapter may loose communication to UCSM as well as preventing the OS from communicating to the network. 

Conditions:
Trying to collect information from the adapter via tech-support or by connecting to the adapter via the CLI will not work. The only way to recover communication to the adapter is by rebooting the blade (which resets the ASIC in the adapter). After communication to the adapter is re-established, admin can match this issue by looking at log for the adapter. The following ASIC (Palo) error will be seen: 
paloerrd.paloerrd ERROR: UIF 0, COS 4 IG_PFIFO stalled

This would be followed by other "feature inoperative" messages and leading to a Uif down / notRunning.
