Description (partial)

A Catalyst 6500 VSS system may experience a crash of the active switch after the 'issu loadversion' command is issued. Since this command reboots the standby switch as well, this would result in a complete loss of service.

This was seen on a Catalyst 6500 VSS system while upgrading from 15.1(2)SY1 to 15.1(2)SY3.
