Summary

Update Instructions

The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 ESM: linux-image-4.4.0-1116-kvm 4.4.0-1116.126 linux-image-4.4.0-236-generic 4.4.0-236.270 linux-image-4.4.0-236-lowlatency 4.4.0-236.270 linux-image-generic 4.4.0.236.242 linux-image-generic-lts-xenial 4.4.0.236.242 linux-image-kvm 4.4.0.1116.113 linux-image-lowlatency 4.4.0.236.242 linux-image-lowlatency-lts-xenial 4.4.0.236.242 linux-image-virtual 4.4.0.236.242 linux-image-virtual-lts-xenial 4.4.0.236.242 Ubuntu 14.04 ESM: linux-image-4.4.0-1115-aws 4.4.0-1115.121 linux-image-4.4.0-236-generic 4.4.0-236.270~14.04.1 linux-image-4.4.0-236-lowlatency 4.4.0-236.270~14.04.1 linux-image-aws 4.4.0.1115.112 linux-image-generic-lts-xenial 4.4.0.236.205 linux-image-lowlatency-lts-xenial 4.4.0.236.205 linux-image-virtual-lts-xenial 4.4.0.236.205 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.
