Just finished upgrading (from Ubuntu 21.10), and it left the box broken in several ways, in an unusable state, see details below.

I have a Z690 gigabyte motherboard, intel alder lake i7, nvidia gpu (of a previous generation).

The upgrade left me with 3 kernels to boot from:

1. If I boot the kernel 5.15.0-27-generic, it freezes just after the message of "loading initial ramdisk"
2. If I boot the kernel 5.13.0-40-generic, it boots on a safe graphics, very low resolution, no sound, no ethernet devices (so no internet).
3. If I boot the kernel 5.13.0-19-generic it also fails, but a little after the boot splash screen ... and then freezes.

$ ip -a

Only shows lo and docker0 interfaces (no ethernet one). But the lspci shows a Ethernet controller: Realtek Semiconductor Co. Ltd. RTL8125 2.5GbE Controller (rev 05), that used to work on the previous version.

Any suggestions ? I'm assuming the first thing to fix is the network. Many thanks!

Ok, I think I fixed it, by changing in /etc/initramfs-tools/initramfs.conf the line MODULES=most to MODULES=dep and then regenerating the initrd images.

I can only assume that there is some bug in one of the modules. I'm now booting the newer 5.17.5 kernel that I installed earlier, and it seems working (even with NVidia driver) as before.

After changing the configuration file, I regenerated the initrd with:

 $ update-initramfs -v -c -k 5.17.5-051705-generic ... $ update-grub
