GNU Linux Debian 11 (should work for Ubuntu too) - compiling latest kernel (Linux/x86 5.17.7) - results in Volume group "name-vg" not found

Dear internet & users & robots & AIs & other entities with access to digital,

one fine day... decided to compile the latest currently available kernel under Debian 11.

last time did that it was Debian 9 and with a bit of tinkering it worked.

now of course - things are different - again.

after a bit of even more tinkering, managed to compile the kernel and all modules (i5 took 100Min)


when it comes to:

sudo make install
sudo make modules_install

it installs...

but after reboot...

it won't find it's previous lvm2 volume group + luks2 encrypted /root

Begin: Running /scripts/init-premount ... done.
Begin: Mounting root file system ...
Begin: Running /scripts/local-top ... Volume group "name-vg" not found

and then falls to "emergency" initramfs prompt...

imho boot partitions should be at least 1GB by now... because have a few kernels installed and the whole thing blows up, because it is out of disk space.

in initramfs prompt:

lvm vgscan

... nothing... does not find the luks2 encrypted /root partition.

but when booting from usb stick

it shows up... ?

(will retry with a 4GB /boot partition and report back X-D)

btw: it was not a problem, getting "back in there" via chroot

and accessing all the data like this:

via this:

actually when chrooted into the luks2 encrypted /root partition,

tried a re-install latest kernel. and was able to watch initrd.img-5.17-amd64 get bigger, and bigger and bigger...

and finally fill up all of the (per default under many distroy) 512MBytes of /boot

thanks :)

You probably haven't included the required modules in the initramfs.

did you consider already [the official wiki FAQ of debian](

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
