The problem can be corrected by updating your system to the following package versions: Ubuntu 23.04: linux-image-6.2.0-1008-starfive 6.2.0-1008.9 linux-image-6.2.0-1015-aws 6.2.0-1015.15 linux-image-6.2.0-1015-oracle 6.2.0-1015.15 linux-image-6.2.0-1016-azure 6.2.0-1016.16 linux-image-6.2.0-1016-kvm 6.2.0-1016.16 linux-image-6.2.0-1016-lowlatency 6.2.0-1016.16 linux-image-6.2.0-1016-lowlatency-64k 6.2.0-1016.16 linux-image-6.2.0-1016-raspi 6.2.0-1016.18 linux-image-6.2.0-1018-gcp 6.2.0-1018.20 linux-image-6.2.0-36-generic 6.2.0-36.37 linux-image-6.2.0-36-generic-64k 6.2.0-36.37 linux-image-6.2.0-36-generic-lpae 6.2.0-36.37 linux-image-aws 6.2.0.1015.16 linux-image-azure 6.2.0.1016.16 linux-image-gcp 6.2.0.1018.18 linux-image-generic 6.2.0.36.36 linux-image-generic-64k 6.2.0.36.36 linux-image-generic-lpae 6.2.0.36.36 linux-image-kvm 6.2.0.1016.16 linux-image-lowlatency 6.2.0.1016.16 linux-image-lowlatency-64k 6.2.0.1016.16 linux-image-oracle 6.2.0.1015.15 linux-image-raspi 6.2.0.1016.19 linux-image-raspi-nolpae 6.2.0.1016.19 linux-image-starfive 6.2.0.1008.11 linux-image-virtual 6.2.0.36.36 Ubuntu 22.04 LTS: linux-image-6.2.0-1015-aws 6.2.0-1015.15~22.04.1 linux-image-6.2.0-1016-azure 6.2.0-1016.16~22.04.1 linux-image-6.2.0-1016-azure-fde 6.2.0-1016.16~22.04.1.1 linux-image-6.2.0-1016-lowlatency 6.2.0-1016.16~22.04.1 linux-image-6.2.0-1016-lowlatency-64k 6.2.0-1016.16~22.04.1 linux-image-6.2.0-1018-gcp 6.2.0-1018.20~22.04.1 linux-image-6.2.0-36-generic 6.2.0-36.37~22.04.1 linux-image-6.2.0-36-generic-64k 6.2.0-36.37~22.04.1 linux-image-6.2.0-36-generic-lpae 6.2.0-36.37~22.04.1 linux-image-aws 6.2.0.1015.15~22.04.1 linux-image-azure 6.2.0.1016.16~22.04.1 linux-image-azure-fde 6.2.0.1016.16~22.04.1.13 linux-image-gcp 6.2.0.1018.20~22.04.1 linux-image-generic-64k-hwe-22.04 6.2.0.36.37~22.04.14 linux-image-generic-hwe-22.04 6.2.0.36.37~22.04.14 linux-image-generic-lpae-hwe-22.04 6.2.0.36.37~22.04.14 linux-image-lowlatency-64k-hwe-22.04 6.2.0.1016.16~22.04.13 linux-image-lowlatency-hwe-22.04 6.2.0.1016.16~22.04.13 linux-image-virtual-hwe-22.04 6.2.0.36.37~22.04.14 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.
