Update instructions:

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

Ubuntu 22.04 LTS
   linux-image-5.15.0-1060-ibm     5.15.0-1060.63
   linux-image-5.15.0-1060-raspi   5.15.0-1060.63
   linux-image-ibm                 5.15.0.1060.56
   linux-image-raspi               5.15.0.1060.58
   linux-image-raspi-nolpae        5.15.0.1060.58

Ubuntu 20.04 LTS
   linux-image-5.15.0-1050-gkeop   5.15.0-1050.57~20.04.1
   linux-image-5.15.0-1060-ibm     5.15.0-1060.63~20.04.1
   linux-image-5.15.0-1067-aws     5.15.0-1067.73~20.04.1
   linux-image-aws                 5.15.0.1067.73~20.04.1
   linux-image-gkeop-5.15          5.15.0.1050.57~20.04.1
   linux-image-ibm                 5.15.0.1060.63~20.04.1

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.
