[lede-17.01.5-x86-64-combined-ext4.img] An error occurred after saved config

[fengchen-lede]

for example

vi /etc/config/network

:wq

reboot

then:

vi /etc/config/network

All characters become countless ‘^@^@’

[jow]

^@^@ is vi's representation of null-bytes, which hints at possible filesystem corruption. Do you see any filesystem related errors in dmesg ?

[fengchen-lede]

cp /etc/config/network /etc/config/network.origin
vi /etc/config/network
:wq

before rebooting

vi /etc/config/network

All look normal.
There is no error about filesystem by ‘dmesg’ .

after rebooting

vi /etc/config/network.original

It's null, nothing.

first boot:

[    3.185484] EXT4-fs error (device sda2): ext4_has_uninit_itable:2883: comm mount_root: Inode table for bg 0 marked as needing zeroing

After modification，and reboot：
