Update instructions:

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

Ubuntu 25.10
  linux-image-6.17.0-1006-realtime  6.17.0-1006.7
  linux-image-6.17.0-1008-raspi   6.17.0-1008.8
  linux-image-6.17.0-14-generic   6.17.0-14.14
  linux-image-6.17.0-14-generic-64k  6.17.0-14.14
  linux-image-generic             6.17.0-14.14
  linux-image-generic-6.17        6.17.0-14.14
  linux-image-generic-64k         6.17.0-14.14
  linux-image-generic-64k-6.17    6.17.0-14.14
  linux-image-raspi               6.17.0-1008.8
  linux-image-raspi-6.17          6.17.0-1008.8
  linux-image-realtime            6.17.0-1006.7
  linux-image-realtime-6.17       6.17.0-1006.7
  linux-image-virtual             6.17.0-14.14
  linux-image-virtual-6.17        6.17.0-14.14

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.
