Update instructions:

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

Ubuntu 22.04 LTS
   linux-image-5.15.0-1080-gcp-fips  5.15.0-1080.89+fips1
                                   Available with Ubuntu Pro
   linux-image-5.15.0-1081-aws-fips  5.15.0-1081.88+fips1
                                   Available with Ubuntu Pro
   linux-image-5.15.0-136-fips     5.15.0-136.147+fips1
                                   Available with Ubuntu Pro
   linux-image-aws-fips            5.15.0.1081.77
                                   Available with Ubuntu Pro
   linux-image-fips                5.15.0.136.77
                                   Available with Ubuntu Pro
   linux-image-gcp-fips            5.15.0.1080.70
                                   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.
