Testing with jammy-server image (which uses 5.15 kernel) it crashes fine.

The general steps are:

1) boot VM with server image
2) apt install kdump-tools (enable kexec, enable kdump)
3) reboot, check crashdump param is set
4) kdump-config show (says ok to dump)
5) echo c | sudo tee /proc/sysrq-trigger

For Focal, upgrade to linux-image-generic-hwe-20.04 kernel and repeat steps 4 and 5.
