Hmm, when C+A+D is hit 7 times we should actually transition
immediately into the "killing spree" phase of shutdown, and local
processes are not waited for anymore, but should receieve SIGKILL
instead.

Any chance you can repeat this with debug logging turned on?
(i.e. systemd.log_level=debug on the kernel cmdline)?

Is flatpak maybe doing some weird fuse stuff, which causes hanging
mounts or so?
