Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.04 LTS:
linux-image-4.15.0-1047-aws 4.15.0-1047.49
linux-image-aws 4.15.0.1047.46

Ubuntu 16.04 LTS:
linux-image-4.15.0-1047-aws 4.15.0-1047.49~16.04.1
linux-image-aws-hwe 4.15.0.1047.47

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.
