Symptom
When a catalyst 3850 or 3650 is being booted using the packages.conf.00- files that are automatically created in flash to restore a previous image the switch will go into a boot loop and the switch will need to be recovered by holding down the mode button to break into the boot cycle and boot an alternative image
Conditions
Packages.conf.00- is being booted in stead of packages.conf
Workaround
copy the packages.conf.00- to packages.conf or any other regular file name and boot this file or use the software roll-back option
Further Problem Description
The boot cycle starts with outputs similar to :
