I enable -proposed and do a dist-upgrade, made sure 21.0.3-0ubuntu0.2 is installed, then reboot and run stress-ng:
$ stress-ng --stack 0 --timeout 300 stress-ng: info: [1936] dispatching hogs: 8 stack stress-ng: info: [1936] successful run completed in 300.88s (5 mins, 0.88 secs)
The desktop session didn't crash so it's still alive.
