Sorry, I missed the request for more information. I retested yesterday,
and it is still possible to crash the system with the above stress-ng
command 4.2.0-6.6 from ppa:canonical-kernel-team/ppa. In fact, it seems
to be 100% reproducible in just seconds. I'm no longer seeing the NULL
pointer dereference - or any additional information on the console - but
that could just be that the console is running too slow. The system no
longer responds to pings - so I don't believe it is just overloaded.
