Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS linux-image-5.15.0-1031-xilinx-zynqmp 5.15.0-1031.35 linux-image-5.15.0-1059-nvidia 5.15.0-1059.60 linux-image-5.15.0-1059-nvidia-lowlatency 5.15.0-1059.60 linux-image-5.15.0-1063-gcp 5.15.0-1063.71 linux-image-5.15.0-113-generic 5.15.0-113.123 linux-image-5.15.0-113-generic-64k 5.15.0-113.123 linux-image-5.15.0-113-generic-lpae 5.15.0-113.123 linux-image-5.15.0-113-lowlatency 5.15.0-113.123 linux-image-5.15.0-113-lowlatency-64k 5.15.0-113.123 linux-image-gcp-lts-22.04 5.15.0.1063.59 linux-image-generic 5.15.0.113.113 linux-image-generic-64k 5.15.0.113.113 linux-image-generic-lpae 5.15.0.113.113 linux-image-lowlatency 5.15.0.113.104 linux-image-lowlatency-64k 5.15.0.113.104 linux-image-nvidia 5.15.0.1059.59 linux-image-nvidia-lowlatency 5.15.0.1059.59 linux-image-virtual 5.15.0.113.113 linux-image-xilinx-zynqmp 5.15.0.1031.35 Ubuntu 20.04 LTS linux-image-5.15.0-113-lowlatency 5.15.0-113.123~20.04.1 linux-image-5.15.0-113-lowlatency-64k 5.15.0-113.123~20.04.1 linux-image-lowlatency-64k-hwe-20.04 5.15.0.113.123~20.04.1 linux-image-lowlatency-hwe-20.04 5.15.0.113.123~20.04.1 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.
