Issues runnig kernel 6.0.1

Question

I have issues when booting the kernel 6.0.1, here the things : I can compile the kernel, but when making update-initramfs -u (for update or -c to create) -k 6.0.1, the initramfs-tools scripts :

/usr/share/initramfs-tools/scripts/init-bottom/ORDER ignored: not executable
/usr/share/initramfs-tools/scripts/local-bottom/ORDER ignored: not executable
/usr/share/initramfs-tools/scripts/panic/ORDER ignored: not executable
/usr/share/initramfs-tools/scripts/init-top/ORDER ignored: not executable
/usr/share/initramfs-tools/scripts/local-premount/ORDER ignored: not executable

But it make it throught anyway. Grub is correctly updated. After reboot, the system correctly boot on the new kernel, but have an issue : kernel couldn't find suitable memory target. So I think that is a initramfs issue. After that, I notice that my new kernel image is far more bigger that the olds ones :

lrwxrwxrwx  1 root root   16 oct.  15 11:33 initrd.img -> initrd.img-6.0.1
-rw-r--r--  1 root root  61M sept. 15 18:25 initrd.img-5.15.0-46-generic
-rw-r--r--  1 root root  61M sept. 15 18:24 initrd.img-5.15.0-47-generic
-rw-r--r--  1 root root  61M sept. 29 18:52 initrd.img-5.15.0-48-generic
-rw-r--r--  1 root root  61M oct.  12 21:21 initrd.img-5.15.0-50-generic
-rw-r--r--  1 root root 482M oct.  16 15:06 initrd.img-6.0.1

So I reduced it with :

root@laptop:/lib/modules/6.0.1# find . -name *.ko -exec strip --strip-unneeded {} *

The image size was similar to others versions' images, and made a update-initramfs. After that, no more memory issue, the kernel ran, but failed to load modules, and entered into rescue mod. The loading-module.service was unable to start, failed because of some rights reasons, if I correctly understood..

If someone had once the same problem, or an idea to fix that, I'll appreciate it. Thanks

Can not find anything that says you can use 6.0.1 only 6.0 so maybe that one is not ready for Ubuntu? — David, Oct 16 '22 at 14:01
Why are you compiling a kernel if you can't do it properly, You an install already compiled mainline kernels easily. — Pilot6, Oct 16 '22 at 15:18
When running a mainline kernel, you're turning your Ubuntu machine into a testing platform. And if you're compiling the kernel yourself, you're experimenting even more. See the below thread for an easy solution to install mainline kernels. — Artur Meinild, Oct 16 '22 at 15:33
Does this answer your question? How do I add the mainline kernel PPA? — Artur Meinild, Oct 16 '22 at 15:33
@ArturMeinild The PPA mentioned in the highest voted answer in the question "How do I add the mainline kernel PPA?" does not exist anymore. — Archisman Panigrahi, Oct 16 '22 at 20:38

Many thanks for your returns. It turns out that it was the lockdown kernel parameter (when configure with make menuconfig), I set it to integrity mode, for increasing security. But it seems that parameter didn't allow the kernel to charge the modules ! It sounds strange, but I turned off the lockdown kernel, re compiled and reinstalled it, now it's work perfectly. Too bad for this security parameter.

# uname -r
6.0.1

@Artur Meinild, @Doug Smythies : Thanks again for the help, I explored yours suggestions too.
