Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS: linux-image-5.15.0-43-generic 5.15.0-43.46 linux-image-5.15.0-43-generic-64k 5.15.0-43.46 linux-image-5.15.0-43-generic-lpae 5.15.0-43.46 linux-image-5.15.0-43-lowlatency 5.15.0-43.46 linux-image-5.15.0-43-lowlatency-64k 5.15.0-43.46 linux-image-generic 5.15.0.43.44 linux-image-generic-64k 5.15.0.43.44 linux-image-generic-64k-hwe-22.04 5.15.0.43.44 linux-image-generic-hwe-22.04 5.15.0.43.44 linux-image-generic-lpae 5.15.0.43.44 linux-image-generic-lpae-hwe-22.04 5.15.0.43.44 linux-image-lowlatency 5.15.0.43.41 linux-image-lowlatency-64k 5.15.0.43.41 linux-image-lowlatency-64k-hwe-22.04 5.15.0.43.41 linux-image-lowlatency-hwe-22.04 5.15.0.43.41 linux-image-oem-20.04 5.15.0.43.44 linux-image-virtual 5.15.0.43.44 linux-image-virtual-hwe-22.04 5.15.0.43.44 Ubuntu 20.04 LTS: linux-image-5.15.0-43-generic 5.15.0-43.46~20.04.1 linux-image-5.15.0-43-generic-64k 5.15.0-43.46~20.04.1 linux-image-5.15.0-43-generic-lpae 5.15.0-43.46~20.04.1 linux-image-5.15.0-43-lowlatency 5.15.0-43.46~20.04.1 linux-image-5.15.0-43-lowlatency-64k 5.15.0-43.46~20.04.1 linux-image-generic-64k-hwe-20.04 5.15.0.43.46~20.04.14 linux-image-generic-hwe-20.04 5.15.0.43.46~20.04.14 linux-image-generic-lpae-hwe-20.04 5.15.0.43.46~20.04.14 linux-image-lowlatency-64k-hwe-20.04 5.15.0.43.46~20.04.13 linux-image-lowlatency-hwe-20.04 5.15.0.43.46~20.04.13 linux-image-virtual-hwe-20.04 5.15.0.43.46~20.04.14 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.
