I strongly suspect you are running out of RAM due to lang/rust not respecting MAKE_JOBS and linking in parallel, killing Xorg.
I've seen the same. You can tell if normal shutdown works fine and you get a message in UVM about Xorg being killed So it's three bugs: - lang/rust doesn't respect MAKE_JOBS - Xorg being killed like so is exceptionally fatal, we don't recover from it ... this should be possible to fix now. - We could try to avoid killing Xorg in these circumstances (this behaviour is caused by something called 'memory overcommit') as a short term solution: - Add more swap, so it doesn't blow up
