Public bug reported: With "linux-image-5.13.0-27-generic" on Ubuntu 20.04.3 LTS, my notebook (Thinkpad T14) crashes when waking up after being suspended. The screen displays what I would describe as "colourful snow" with some vertical stripes on the right edge of the display. The only thing I can do is power off the machine by holding the power button for several seconds and then restart.
With "linux-image-5.11.0-46-generic", this does not happen.
