Update instructions:

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

Ubuntu 24.04 LTS
linux-image-6.8.0-1039-nvidia 6.8.0-1039.42
linux-image-6.8.0-1039-nvidia-64k 6.8.0-1039.42
linux-image-6.8.0-1039-nvidia-lowlatency 6.8.0-1039.42.1
linux-image-6.8.0-1039-nvidia-lowlatency-64k 6.8.0-1039.42.1
linux-image-nvidia 6.8.0-1039.42
linux-image-nvidia-6.8 6.8.0-1039.42
linux-image-nvidia-64k 6.8.0-1039.42
linux-image-nvidia-64k-6.8 6.8.0-1039.42
linux-image-nvidia-lowlatency 6.8.0-1039.42.1
linux-image-nvidia-lowlatency-6.8 6.8.0-1039.42.1
linux-image-nvidia-lowlatency-64k 6.8.0-1039.42.1
linux-image-nvidia-lowlatency-64k-6.8 6.8.0-1039.42.1

Ubuntu 22.04 LTS
linux-image-6.8.0-1039-nvidia 6.8.0-1039.42~22.04.1
linux-image-6.8.0-1039-nvidia-64k 6.8.0-1039.42~22.04.1
linux-image-nvidia-6.8 6.8.0-1039.42~22.04.1
linux-image-nvidia-64k-6.8 6.8.0-1039.42~22.04.1
linux-image-nvidia-64k-hwe-22.04 6.8.0-1039.42~22.04.1
linux-image-nvidia-hwe-22.04 6.8.0-1039.42~22.04.1

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.
