The problem can be corrected by updating your system to the following package versions: Ubuntu 25.10 linux-image-6.17.0-1014-realtime 6.17.0-1014.16 linux-image-6.17.0-1016-oracle 6.17.0-1016.16 linux-image-6.17.0-1016-oracle-64k 6.17.0-1016.16 linux-image-6.17.0-1017-aws 6.17.0-1017.17 linux-image-6.17.0-1017-aws-64k 6.17.0-1017.17 linux-image-6.17.0-1017-azure 6.17.0-1017.17 linux-image-6.17.0-1018-raspi 6.17.0-1018.18 linux-image-6.17.0-35-generic 6.17.0-35.35 linux-image-6.17.0-35-generic-64k 6.17.0-35.35 linux-image-aws 6.17.0-1017.17 linux-image-aws-6.17 6.17.0-1017.17 linux-image-aws-64k 6.17.0-1017.17 linux-image-aws-64k-6.17 6.17.0-1017.17 linux-image-azure 6.17.0-1017.17 linux-image-azure-6.17 6.17.0-1017.17 linux-image-generic 6.17.0-35.35 linux-image-generic-6.17 6.17.0-35.35 linux-image-generic-64k 6.17.0-35.35 linux-image-generic-64k-6.17 6.17.0-35.35 linux-image-oracle 6.17.0-1016.16 linux-image-oracle-6.17 6.17.0-1016.16 linux-image-oracle-64k 6.17.0-1016.16 linux-image-oracle-64k-6.17 6.17.0-1016.16 linux-image-raspi 6.17.0-1018.18 linux-image-raspi-6.17 6.17.0-1018.18 linux-image-realtime 6.17.0-1014.16 linux-image-realtime-6.17 6.17.0-1014.16 linux-image-virtual 6.17.0-35.35 linux-image-virtual-6.17 6.17.0-35.35 Ubuntu 24.04 LTS linux-image-6.17.0-1014-realtime 6.17.0-1014.16~24.04.1 Available with Ubuntu Pro linux-image-6.17.0-1016-oracle 6.17.0-1016.16~24.04.1 linux-image-6.17.0-1016-oracle-64k 6.17.0-1016.16~24.04.1 linux-image-6.17.0-1017-azure 6.17.0-1017.17~24.04.1 linux-image-6.17.0-1021-nvidia 6.17.0-1021.21 linux-image-6.17.0-1021-nvidia-64k 6.17.0-1021.21 linux-image-6.17.0-1024-oem 6.17.0-1024.24 linux-image-6.17.0-35-generic 6.17.0-35.35~24.04.1 linux-image-6.17.0-35-generic-64k 6.17.0-35.35~24.04.1 linux-image-azure 6.17.0-1017.17~24.04.1 linux-image-azure-6.17 6.17.0-1017.17~24.04.1 linux-image-generic-6.17 6.17.0-35.35~24.04.1 linux-image-generic-64k-6.17 6.17.0-35.35~24.04.1 linux-image-generic-64k-hwe-24.04 6.17.0-35.35~24.04.1 linux-image-generic-hwe-24.04 6.17.0-35.35~24.04.1 linux-image-nvidia-6.17 6.17.0-1021.21 linux-image-nvidia-64k-6.17 6.17.0-1021.21 linux-image-nvidia-64k-hwe-24.04 6.17.0-1021.21 linux-image-nvidia-hwe-24.04 6.17.0-1021.21 linux-image-oem-24.04 6.17.0-1024.24 linux-image-oem-24.04a 6.17.0-1024.24 linux-image-oem-24.04b 6.17.0-1024.24 linux-image-oem-24.04c 6.17.0-1024.24 linux-image-oem-24.04d 6.17.0-1024.24 linux-image-oem-6.17 6.17.0-1024.24 linux-image-oracle 6.17.0-1016.16~24.04.1 linux-image-oracle-6.17 6.17.0-1016.16~24.04.1 linux-image-oracle-64k 6.17.0-1016.16~24.04.1 linux-image-oracle-64k-6.17 6.17.0-1016.16~24.04.1 linux-image-realtime-6.17 6.17.0-1014.16~24.04.1 Available with Ubuntu Pro linux-image-realtime-hwe-24.04 6.17.0-1014.16~24.04.1 Available with Ubuntu Pro linux-image-virtual-6.17 6.17.0-35.35~24.04.1 linux-image-virtual-hwe-24.04 6.17.0-35.35~24.04.1 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.
