Symptom

Description ************ When we issue "copy run start all" on 4K platforms , the router copies some default commands into start-up. After that when we try to reload the router, it tries to insert those default commands from start-up and we see the following: % Invalid input detected at '^' marker. platform trace boottime slot max bay 0 process R0 level emd ^ % Invalid input detected at '^' marker. platform trace boottime slot max bay 0 process R0 level forwarding-manager ^ % Invalid input detected at '^' marker. platform trace boottime slot max bay 0 process R0 level ios ^ % Invalid input detected at '^' marker. platform trace boottime slot max bay 0 process R0 level pluggable-services ^ % Invalid input detected at '^' marker. platform trace boottime slot max bay 0 process R0 level virt-manager ^ % Invalid input detected at '^' marker. This process goes on for a longtime and the router finally gets stuck. To get out of that situation, we power-cycle the device and break the boot sequence and change the config reg to bypass the start-up, then only We could recover the router.

Conditions

Steps to reproduce ****************** 1. Load the IOS 15.5(3) S6 on 4431 2. We issue ?copy run start all? and check start-up config, you should see a lot of platform related commands. 3. I reload the router and monitor the status in console. 4. After booting-up , Router tries to issue commands from the start-up config and we see the above errors 5. After 15 mins, router is completely stuck! We waited for 30-40 mins but it never came back up. 6. We had to get into Rommon and do boot recovery.

Workaround

Workaround ************** 1. Don't use "copy run start all" 2. Get into Rommon mode and do a boot recovery so that we can skip the startup config (confreg=0x2142)
