which kernel config to turn from module to build-in on ubuntu-mate 20.04.2 LTS

I have Ubuntu 20.04.2 LTS where i want to run my own kernel, so I did :

make -j 3 allmodconfigmake -j 3 bzImagemake -j 3 modulessudo make -j 3 modules_installsudo make install

in recovery mode, the kernel panics in a softlockupin normal mode, the kernel also does not bootthe root file system is lvm encrypted....

How to fix this ?
