工具与软件：
1、我们进行了16小时的高温和低温压力测试,发现我们的睡眠文件在压力测试后损坏
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 μ s 与、的睡眠文件 MD5相比、发现了更改

3、log
