make a correction, the previous 'dmesg log' description was not accurate.
I referred that to the kernel log captured via 'journalctl' after recycling the power. I should use kernel log rather than 'dmesg log' to avoid the confusion.

As mentioned in my "previous previous" reply, the user have to recycle power to reset the system.
When issue occurred, keyboard/mouse didn't work. 'demsg' and ssh didn't work either.

I have no idea.
