Tool/software:
1、We took a high and low temperature pressure test for 16 hours and found that our sleep file was damaged after the pressure test
root@j721e-evm:~# ls -l /bin/ [ 7052.671361] EXT4-fs error (device mmcblk0p2): ext4_lookup:1851: inode #39: comm ls: iget: bad extended attribute block 141733921779 ls: cannot access '/bin/sleep': Structure needs cleaning lrwxrwxrwx 1 1083 1083 14 Mar 9 2018 sh -> /bin/bash.bash l????????? ? ? ? ? ? sleep -rwxr-xr-x 1 1083 1083 39496 Mar 9 2018 sleep.coreutils
2、Compared with the normal sleep file md5, changes were found
