Update instructions:

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

Ubuntu 22.04 LTS
  linux-image-5.15.0-1037-nvidia-tegra  5.15.0-1037.37
  linux-image-5.15.0-1037-nvidia-tegra-rt  5.15.0-1037.37
  linux-image-5.15.0-1089-azure   5.15.0-1089.98
  linux-image-azure-lts-22.04     5.15.0.1089.87
  linux-image-nvidia-tegra        5.15.0.1037.37
  linux-image-nvidia-tegra-rt     5.15.0.1037.37

Ubuntu 20.04 LTS
  linux-image-5.15.0-1089-azure   5.15.0-1089.98~20.04.1
  linux-image-azure               5.15.0.1089.98~20.04.1
  linux-image-azure-cvm           5.15.0.1089.98~20.04.1

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.
