Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS: linux-image-5.4.0-1020-bluefield 5.4.0-1020.23 linux-image-5.4.0-1048-kvm 5.4.0-1048.50 linux-image-5.4.0-89-generic 5.4.0-89.100 linux-image-5.4.0-89-generic-lpae 5.4.0-89.100 linux-image-5.4.0-89-lowlatency 5.4.0-89.100 linux-image-bluefield 5.4.0.1020.21 linux-image-generic 5.4.0.89.93 linux-image-generic-lpae 5.4.0.89.93 linux-image-kvm 5.4.0.1048.47 linux-image-lowlatency 5.4.0.89.93 linux-image-oem 5.4.0.89.93 linux-image-oem-osp1 5.4.0.89.93 linux-image-virtual 5.4.0.89.93 Ubuntu 18.04 LTS: linux-image-5.4.0-1055-gcp 5.4.0-1055.59~18.04.1 linux-image-5.4.0-89-generic 5.4.0-89.100~18.04.1 linux-image-5.4.0-89-generic-lpae 5.4.0-89.100~18.04.1 linux-image-5.4.0-89-lowlatency 5.4.0-89.100~18.04.1 linux-image-gcp 5.4.0.1055.41 linux-image-generic-hwe-18.04 5.4.0.89.100~18.04.79 linux-image-generic-lpae-hwe-18.04 5.4.0.89.100~18.04.79 linux-image-lowlatency-hwe-18.04 5.4.0.89.100~18.04.79 linux-image-oem 5.4.0.89.100~18.04.79 linux-image-oem-osp1 5.4.0.89.100~18.04.79 linux-image-snapdragon-hwe-18.04 5.4.0.89.100~18.04.79 linux-image-virtual-hwe-18.04 5.4.0.89.100~18.04.79 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.
