Update Instructions

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

Ubuntu 22.04 LTS
  linux-image-5.15.0-134-generic  5.15.0-134.145
  linux-image-5.15.0-134-generic-64k  5.15.0-134.145
  linux-image-5.15.0-134-generic-lpae  5.15.0-134.145
  linux-image-5.15.0-134-lowlatency  5.15.0-134.145
  linux-image-5.15.0-134-lowlatency-64k  5.15.0-134.145
  linux-image-generic             5.15.0.134.133
  linux-image-generic-64k         5.15.0.134.133
  linux-image-generic-lpae        5.15.0.134.133
  linux-image-lowlatency          5.15.0.134.121
  linux-image-lowlatency-64k      5.15.0.134.121
  linux-image-virtual             5.15.0.134.133

Ubuntu 20.04 LTS
  linux-image-5.15.0-134-lowlatency  5.15.0-134.145~20.04.1
  linux-image-5.15.0-134-lowlatency-64k  5.15.0-134.145~20.04.1
  linux-image-lowlatency-64k-hwe-20.04  5.15.0.134.145~20.04.1
  linux-image-lowlatency-hwe-20.04  5.15.0.134.145~20.04.1

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.
