Solution
This message means that there is an issue with flash memory. Most probably there is a bad block and system tried to access it.
To recover from this issue is to format boot device (flash memory) and reload same firmware version as before and then restore configuration from backup file or reconfigure unit from scratch manually if you don't have update configuration backup.
