Update Instructions

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

Ubuntu 22.04 LTS
  linux-image-5.15.0-1036-xilinx-zynqmp  5.15.0-1036.40
  linux-image-xilinx-zynqmp       5.15.0.1036.40

Ubuntu 20.04 LTS
  linux-image-5.15.0-1063-ibm     5.15.0-1063.66~20.04.1
  linux-image-5.15.0-1068-oracle  5.15.0-1068.74~20.04.1
  linux-image-ibm                 5.15.0.1063.66~20.04.1
  linux-image-oracle              5.15.0.1068.74~20.04.1

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.
