Update instructions:

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

Ubuntu 22.04 LTS
  linux-image-6.8.0-60-generic    6.8.0-60.63~22.04.1
  linux-image-6.8.0-60-generic-64k  6.8.0-60.63~22.04.1
  linux-image-generic-64k-hwe-22.04  6.8.0-60.63~22.04.1
  linux-image-generic-hwe-22.04   6.8.0-60.63~22.04.1
  linux-image-oem-22.04           6.8.0-60.63~22.04.1
  linux-image-oem-22.04a          6.8.0-60.63~22.04.1
  linux-image-oem-22.04b          6.8.0-60.63~22.04.1
  linux-image-oem-22.04c          6.8.0-60.63~22.04.1
  linux-image-oem-22.04d          6.8.0-60.63~22.04.1
  linux-image-virtual-hwe-22.04   6.8.0-60.63~22.04.1

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.
