Hi 2503029332@qq.com
... Illegal instruction
That indicates the code is not compatible with your processor.

Many lines showing your kernel config is not compatible.
The only barriers that can stop you are the ones you create yourself.

You need to recompile /sbin/udevadm for your hardware.

Where did that come from? I don't think it's one of our kernels, is it?
It looks like you mixed a kernel from somewhere else with our initrd.

You need to recompile /sbin/udevadm for your hardware.
And  /sbin/udevd,  and possibly other programs contained in the initrd that haven't tried to execute yet.

It's also likely you'll these have issues with extensions. Also, kernel modules won't match the kernel.
