I have a problem that device load up to U-Boot after power failure. This issue appear sporadically. I want to know what can cause it and how shud I prevent it. The system is Debian 8.1 and run on embedded device. I want to know what parameters responsible that system enter to U-boot and why they get such values during power failure.

Just to mention system not loaded to runlevel 1 , or emergency mode. It just stuck on U-Boot.

System details : Debian 8.1 system is use ARM CPU . 2 GB RAM 4 GB flash bootloader is : U-Boot.

Le me know if more information is needed
