Problem Description
Cisco discovered a bug in the ISDN code that can cause router halts on routers with a MPC860 Power PC processor, such as in the Cisco 2600 Series and in the MC3810. The router halts due to a watchdog timeout. This problem is described in DDTS CSCdk62967 for the Cisco 2600 Series and DDTS CSCdk58904 for the MC3810.
Background
This problem was originally introduced with DDTS CSCdk55215.
