Need to Use Recovery Mode to Boot When I Change Kernel

I have setup a VMware with Ubuntu 20.04 and my kernel version is 5.4.

I download kernel version 4.4 and write some simple system call.

And then compile and install to my system.

When I boot with kernel 4.4,it stuck before login screen show.

I even can't change to tty1~7

But in recovery mode and resume normal boot,I can get to the login screen with no error.

And my system call work fine.

So I assume that my system call is not reason for cause this problem.

And I check the journalctl -b and fix some error but not work with this problem
