Summary
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: linux-image-4.4.0-1082-kvm 4.4.0-1082.91 linux-image-4.4.0-1117-aws 4.4.0-1117.131 linux-image-4.4.0-1141-raspi2 4.4.0-1141.151 linux-image-4.4.0-1145-snapdragon 4.4.0-1145.155 linux-image-4.4.0-193-generic 4.4.0-193.224 linux-image-4.4.0-193-generic-lpae 4.4.0-193.224 linux-image-4.4.0-193-lowlatency 4.4.0-193.224 linux-image-4.4.0-193-powerpc-e500mc 4.4.0-193.224 linux-image-4.4.0-193-powerpc-smp 4.4.0-193.224 linux-image-4.4.0-193-powerpc64-emb 4.4.0-193.224 linux-image-4.4.0-193-powerpc64-smp 4.4.0-193.224 linux-image-aws 4.4.0.1117.122 linux-image-generic 4.4.0.193.199 linux-image-generic-lpae 4.4.0.193.199 linux-image-kvm 4.4.0.1082.80 linux-image-lowlatency 4.4.0.193.199 linux-image-powerpc-e500mc 4.4.0.193.199 linux-image-powerpc-smp 4.4.0.193.199 linux-image-powerpc64-emb 4.4.0.193.199 linux-image-powerpc64-smp 4.4.0.193.199 linux-image-raspi2 4.4.0.1141.141 linux-image-snapdragon 4.4.0.1145.137 linux-image-virtual 4.4.0.193.199 Ubuntu 14.04 ESM: linux-image-4.4.0-1081-aws 4.4.0-1081.85 linux-image-4.4.0-193-generic 4.4.0-193.224~14.04.1 linux-image-4.4.0-193-generic-lpae 4.4.0-193.224~14.04.1 linux-image-4.4.0-193-lowlatency 4.4.0-193.224~14.04.1 linux-image-aws 4.4.0.1081.78 linux-image-generic-lpae-lts-xenial 4.4.0.193.169 linux-image-generic-lts-xenial 4.4.0.193.169 linux-image-lowlatency-lts-xenial 4.4.0.193.169 linux-image-virtual-lts-xenial 4.4.0.193.169 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.
