Compiling a new kernel for debian

[manatails]

Hi, I am trying to use Blackbird with the newest linux kernel.

I'm using the classic commands:

cd linux-5.x.x
cp -v /boot/config-$(uname -r) .config
make olddefconfig
make -j16 deb-pkg

the new kernel builds, fine, boots fine but it cannot reboot or shutdown the computer...

Any words about what could be done about this?

What happens when you try to? What do you see in dmesg?

In any case, I don't understand why the Debian site lists the "linux-package" package when it no longer exists. Obviously the procedure they give does not work because that package does not download and honestly I can not understand all this ... What replaces that package and why is it not mentioned anywhere?

I just left the computer turned on after it froze, then a few minutes later I got this in the terminal
