Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 24.04 LTS
linux-image-6.8.0-1022-azure-nvidia 6.8.0-1022.23
linux-image-6.8.0-1034-azure 6.8.0-1034.39

linux-image-azure-fde-6.8 6.8.0-1034.39
linux-image-azure-fde-lts-24.04 6.8.0-1034.39
linux-image-azure-lts-24.04 6.8.0-1034.39
linux-image-azure-nvidia 6.8.0-1022.23
linux-image-azure-nvidia-6.8 6.8.0-1022.23
linux-image-azure-nvidia-lts-24.04 6.8.0-1022.23
Ubuntu 22.04 LTS
linux-image-6.8.0-1034-azure 6.8.0-1034.39~22.04.1
linux-image-6.8.0-1034-azure-fde 6.8.0-1034.39~22.04.1
linux-image-azure 6.8.0-1034.39~22.04.1
linux-image-azure-6.8 6.8.0-1034.39~22.04.1
linux-image-azure-fde 6.8.0-1034.39~22.04.1
linux-image-azure-fde-6.8 6.8.0-1034.39~22.04.1
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.
