You are not using the pure jetpack image, right? Is it a custom carrier board?

Could you try the jetpack BSP first?

Did this work previously? Was this flashed recently? Which release is this from?

This subset of the log is of interest:

[    7.906257] EXT4-fs (mmcblk0p1): recovery complete
[    7.906841] EXT4-fs (mmcblk0p1): mounted filesystem with ordered data mode. Opts: (null)
[    7.906872] VFS: Mounted root (ext4 filesystem) on device 179:1.
[    7.909181] devtmpfs: mounted
[    7.911038] Freeing unused kernel memory: 8512K
[    7.921886] Starting init: /etc/init exists but couldn't execute it (error -13)

The log makes me wonder if the system has been shutdown correctly, or if it has lost power without proper shutdown. If the login failed and you had to pull the power, then this is normal, but if the filesystem had to be repaired like this due to some other issue, then this would perhaps be a cause rather than a mere symptom. “init” is at the heart of everything which follows the kernel load (the kernel is PID 0, init is PID 1), and is a directory which should contain different configuration files.

We often cut off power directly.This may be the cause of the problem,thank you very much.

This implies you will probably have to flash again. You could attempt to recover a clone from a host PC if the content is valuable, but proper shutdown is mandatory if you want to avoid possible failure (the only way to guarantee non-corrupt partition when you will be abruptly cutting power is via synchronous mount, and this will not only destroy performance, this will also drastically degrade the life of any solid state memory).
