Update instructions:

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

Ubuntu 20.04 LTS
  linux-image-5.4.0-1099-bluefield  5.4.0-1099.106
  linux-image-5.4.0-1143-gcp      5.4.0-1143.152
  linux-image-5.4.0-1145-azure    5.4.0-1145.152
  linux-image-azure-lts-20.04     5.4.0.1145.139
  linux-image-bluefield           5.4.0.1099.95
  linux-image-gcp-lts-20.04       5.4.0.1143.145

Ubuntu 18.04 LTS
  linux-image-5.4.0-1086-ibm      5.4.0-1086.91~18.04.1
				  Available with Ubuntu Pro
  linux-image-5.4.0-1143-gcp      5.4.0-1143.152~18.04.1
				  Available with Ubuntu Pro
  linux-image-5.4.0-1145-azure    5.4.0-1145.152~18.04.1
				  Available with Ubuntu Pro
  linux-image-azure               5.4.0.1145.152~18.04.1
				  Available with Ubuntu Pro
  linux-image-gcp                 5.4.0.1143.152~18.04.1
				  Available with Ubuntu Pro
  linux-image-ibm                 5.4.0.1086.91~18.04.1
				  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.
