Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 20.04 LTS
linux-image-5.15.0-1091-azure 5.15.0-1091.100~20.04.1
Available with Ubuntu Pro
linux-image-azure 5.15.0.1091.100~20.04.1
Available with Ubuntu Pro
linux-image-azure-cvm 5.15.0.1091.100~20.04.1
Available with Ubuntu Pro
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.
