Update Instructions

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

Ubuntu 25.10
  linux-image-6.17.0-1007-gcp     6.17.0-1007.7
  linux-image-6.17.0-1007-gcp-64k  6.17.0-1007.7
  linux-image-gcp                 6.17.0-1007.7
  linux-image-gcp-6.17            6.17.0-1007.7
  linux-image-gcp-64k             6.17.0-1007.7
  linux-image-gcp-64k-6.17        6.17.0-1007.7

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.
