The problem can be corrected by updating your system to the following package versions: Ubuntu 23.10: linux-image-6.5.0-1005-starfive 6.5.0-1005.6 linux-image-6.5.0-1007-laptop 6.5.0-1007.10 linux-image-6.5.0-1008-raspi 6.5.0-1008.11 linux-image-6.5.0-1009-azure 6.5.0-1009.9 linux-image-6.5.0-1009-azure-fde 6.5.0-1009.9 linux-image-6.5.0-1011-aws 6.5.0-1011.11 linux-image-6.5.0-1013-oracle 6.5.0-1013.13 linux-image-6.5.0-14-generic 6.5.0-14.14 linux-image-6.5.0-14-generic-64k 6.5.0-14.14 linux-image-6.5.0-14-lowlatency 6.5.0-14.14.1 linux-image-6.5.0-14-lowlatency-64k 6.5.0-14.14.1 linux-image-aws 6.5.0.1011.11 linux-image-azure 6.5.0.1009.11 linux-image-azure-fde 6.5.0.1009.11 linux-image-generic 6.5.0.14.16 linux-image-generic-64k 6.5.0.14.16 linux-image-generic-lpae 6.5.0.14.16 linux-image-kvm 6.5.0.14.16 linux-image-laptop-23.10 6.5.0.1007.10 linux-image-lowlatency 6.5.0.14.14.12 linux-image-lowlatency-64k 6.5.0.14.14.12 linux-image-oracle 6.5.0.1013.13 linux-image-raspi 6.5.0.1008.9 linux-image-raspi-nolpae 6.5.0.1008.9 linux-image-starfive 6.5.0.1005.7 linux-image-virtual 6.5.0.14.16 Ubuntu 22.04 LTS: linux-image-6.5.0-1009-oem 6.5.0-1009.10 linux-image-oem-22.04d 6.5.0.1009.11 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.
