Update Instructions

The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS linux-image-5.15.0-1091-raspi 5.15.0-1091.94 linux-image-raspi 5.15.0.1091.89 linux-image-raspi-5.15 5.15.0.1091.89 linux-image-raspi-nolpae 5.15.0.1091.89 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
