I am currently having trouble finding a tutorial on how to downgrade the kernel of Ubuntu Server 22.04.4 LTS on the Raspberry Pi.
The currently installed kernel version is 5.15.0-1050-raspi.
The Pi version of Ubuntu Server 22.04 LTS does not have GRUB installed and is not an option for me either.
The reason why I want to downgrade the kernel: I currently have the problem that my Docker backup based on CIFS shares fails due to I/O errors on reading the share folder.
In the current kernel for Ubuntu 22.04 there is an already confirmed bug, see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2060780
My notebooks installed with Linux Mint are also affected by this bug.
I would like to find out if this also affects the current kernel in the Raspi version.
The Raspberry runs in headless mode and in an DMZ, so the only way to administrate the system is SSH.
