PROBLEM:  (CLD ZPOBC0559)                 (Patch ID: OSF425-201)
********
This patch fixes a problem that occurs on a system running ATM. The system
panics with a "kernel memory fault" due to a simple lock time violation.

Prior to the crash, the pvc flag is observed as stale on a permanent virtual
circuit.  The crash occurs after the pvc is deleted with the following command:

  # atmconfig -pvc .....

A sample stack trace is shown in the following example:
