Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: linux-image-5.0.0-1051-gke 5.0.0-1051.53 linux-image-5.3.0-1037-raspi2 5.3.0-1037.39 linux-image-5.3.0-1040-gke 5.3.0-1040.43 linux-image-5.3.0-70-generic 5.3.0-70.66 linux-image-5.3.0-70-lowlatency 5.3.0-70.66 linux-image-gke-5.0 5.0.0.1051.35 linux-image-gke-5.3 5.3.0.1040.23 linux-image-gkeop-5.3 5.3.0.70.127 linux-image-raspi2-hwe-18.04 5.3.0.1037.26 Ubuntu 14.04 ESM: linux-image-3.13.0-184-generic 3.13.0-184.235 linux-image-3.13.0-184-generic-lpae 3.13.0-184.235 linux-image-3.13.0-184-lowlatency 3.13.0-184.235 linux-image-3.13.0-184-powerpc-e500 3.13.0-184.235 linux-image-3.13.0-184-powerpc-e500mc 3.13.0-184.235 linux-image-3.13.0-184-powerpc-smp 3.13.0-184.235 linux-image-3.13.0-184-powerpc64-emb 3.13.0-184.235 linux-image-3.13.0-184-powerpc64-smp 3.13.0-184.235 linux-image-generic 3.13.0.184.193 linux-image-generic-lpae 3.13.0.184.193 linux-image-generic-pae 3.13.0.184.193 linux-image-highbank 3.13.0.184.193 linux-image-lowlatency 3.13.0.184.193 linux-image-lowlatency-pae 3.13.0.184.193 linux-image-omap 3.13.0.184.193 linux-image-powerpc-e500 3.13.0.184.193 linux-image-powerpc-e500mc 3.13.0.184.193 linux-image-powerpc-smp 3.13.0.184.193 linux-image-powerpc64-emb 3.13.0.184.193 linux-image-powerpc64-smp 3.13.0.184.193 linux-image-server 3.13.0.184.193 linux-image-virtual 3.13.0.184.193 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.
