Power down test,the system halt some times! It seems that some file in filesystem was disturbed!

 

What can I do to protect the system when power down?

 

My system is IP-PBX,based BF533.

 

Thanks!

Unmount your file system before power down the system.

use a filesystem that is designed for random power failures.  like jffs2 or ubifs.

 

you didnt say what filesystem type you're using or where the storage is ...

2008R1 is pretty old at this point, and yaffs2 is dead, so you'll either have to upgrade or debug the issue on your side
