Bug Description

In your logs I see see vesafb warnings and it needs to be disabled.

NVRM: Your system is not currently configured to drive a VGA console
4月 01 07:55:58 ATC kernel: NVRM: on the primary VGA device. The NVIDIA Linux graphics driver
4月 01 07:55:58 ATC kernel: NVRM: requires the use of a text-mode VGA console. Use of other console

4月 01 07:55:58 ATC kernel: NVRM: corruption and stability problems, and is not supported.

To disable it,
Code:
Add 'video=vesafb:off vga=normal'
on the kernel command line in the bootloader configuration file.

Then reboot.

Let me know if this helps or not and if not describe the problem and generate and attach new logs.
