Update instructions:

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

Ubuntu 25.04
   linux-image-6.14.0-1007-azure   6.14.0-1007.7
   linux-image-6.14.0-1007-azure-fde  6.14.0-1007.7
   linux-image-azure               6.14.0-1007.7
   linux-image-azure-fde           6.14.0-1007.7

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.
