Here's one for the Tips and Techniques manual.
Recently an updated Debian 11 backport kernel has been released.
Existing kernel in my Debian 11 VM:
linux-image-5.18.0-0.deb11.4-4-arm64
Upgraded to:
linux-image-5.19.0-0.deb11.2-arm64
After the upgrade the VM boots and everything I checked so far seems to be in proper working order. And that includes dynamic resizing.
apt-get install linux-image-5.19.0-0.deb11.2-arm64/bullseye-backports
Enjoy!
