Update Instructions

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

Ubuntu 18.04 LTS
  linux-image-4.15.0-235-generic  4.15.0-235.247
				  Available with Ubuntu Pro
  linux-image-4.15.0-235-lowlatency  4.15.0-235.247
				  Available with Ubuntu Pro
  linux-image-generic             4.15.0.235.219
				  Available with Ubuntu Pro
  linux-image-lowlatency          4.15.0.235.219
				  Available with Ubuntu Pro
  linux-image-virtual             4.15.0.235.219
				  Available with Ubuntu Pro

Ubuntu 16.04 LTS
  linux-image-4.15.0-235-generic  4.15.0-235.247~16.04.1
				  Available with Ubuntu Pro
  linux-image-4.15.0-235-lowlatency  4.15.0-235.247~16.04.1
				  Available with Ubuntu Pro
  linux-image-generic-hwe-16.04   4.15.0.235.247~16.04.1
				  Available with Ubuntu Pro
  linux-image-lowlatency-hwe-16.04  4.15.0.235.247~16.04.1
				  Available with Ubuntu Pro
  linux-image-oem                 4.15.0.235.247~16.04.1
				  Available with Ubuntu Pro
  linux-image-virtual-hwe-16.04   4.15.0.235.247~16.04.1
				  Available with Ubuntu Pro

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.
