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

Kernel from https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.14.1.tar.xz

make -j 3 allmodconfig
make -j 3 bzImage
make -j 3 modules
sudo make -j 3 modules_install
sudo make install

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

How to fix this ?

Can you boot with another kernel from the advanced options in the grub screen? – Archisman Panigrahi Sep 04 '21 at 06:57
onlyl with the standard ubuntu kernel – Thorsten Kiefer Sep 04 '21 at 07:17
So boot with the working kernel, and remove the faulty ones. – Archisman Panigrahi Sep 04 '21 at 07:19
actually i wanted to know why the kernel.org kernel does not boot, and fix that – Thorsten Kiefer Sep 04 '21 at 07:48
Then please edit your question appropriately with which exact kernel you tried to install. – Archisman Panigrahi Sep 04 '21 at 07:49
I added a link to the kernel source – Thorsten Kiefer Sep 04 '21 at 08:11
You can download .deb packages of these kernels from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.14.1/ (and install them in your own risk -- there are reasons the Ubuntu kernel team did not release them as updates yet). – Archisman Panigrahi Sep 04 '21 at 09:16
Why do you want to upgrade the kernel? Does something not work correctly? – Archisman Panigrahi Sep 04 '21 at 09:17
Pentium silver sound does not work and for security reasons, and simply the philosophy, that the kernel.org kernel should work like this / so for testing resons – Thorsten Kiefer Sep 04 '21 at 09:45
Pentium silver sound does not work -- You can ask a new question about that and for security reasons -- The existing kernels are regularly patched for security. kernel.org kernel should work like this - You should edit your question to specify that you want to build a kernel.org kernel and ask how to do it. – Archisman Panigrahi Sep 04 '21 at 13:49
Try following this compile/install method. – Doug Smythies Sep 04 '21 at 14:54
