Update Instructions

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

Ubuntu 22.04 LTS
   linux-image-5.15.0-1084-ibm     5.15.0-1084.87
   linux-image-5.15.0-1084-raspi   5.15.0-1084.87
   linux-image-5.15.0-1085-intel-iotg  5.15.0-1085.91
   linux-image-5.15.0-1088-oracle  5.15.0-1088.94
   linux-image-ibm                 5.15.0.1084.80
   linux-image-ibm-5.15            5.15.0.1084.80
   linux-image-intel-iotg          5.15.0.1085.85
   linux-image-intel-iotg-5.15     5.15.0.1085.85
   linux-image-oracle-5.15         5.15.0.1088.84
   linux-image-oracle-lts-22.04    5.15.0.1088.84
   linux-image-raspi               5.15.0.1084.82
   linux-image-raspi-5.15          5.15.0.1084.82
   linux-image-raspi-nolpae        5.15.0.1084.82

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.
