Reboot the SW,

Are you save the config, 

The SW need vlan to pass the hello between two router, check vlan after reboot.

Hello,

On your Active SW you don't have Etherchannel set up but on your STANDBY you do. One side can send on both links while the other cant so that could be the reason you are seeing flapping.

Hope that helps

If the HSRP state is changing, then the HSRP reply isn't coming from one device to the other in the appropriate amount of time it expects.

Can you run the debug command on both active and standby devices and share log.
