Description (partial)

Third party CPE Routers might not complete PPP IPCP negociation
after an upgrade from IOS 12.0S to IOS-XR 3.8.0

This has been seen on a scaled configuration where a number of these
devices is connected onto the same GSR Line Card.
The problem can be reproduced at system or LC reload when all the CPE's
re-establish the PPP connectivity at the same time.
