Description (partial)

Simulating an intermediate session routing (ISR) watchdog using a busy-loop delay in an ISR, results in an incorrect traceback. Further, an infinite loop in the ISR results in no ISR watchdog functionality at all.

This issue is seen when the "scheduler isr-watchdog" configuration command is not present
in the router configuration. This command is used to enable the ISR watchdog functionality. 
NOTE: This issue affects only PowerPC-based NPEs, for example, NPE-G2 and c7201 on the Cisco uBR 7200 series routers. MIPS-based NPEs are not affected.
