I have seen this oops twice; I didn't report the issue first time round
as the machine I was using had been powered down and I was unable to
collect any logs. I happened to notice the stacktrace in my serial
console window so I tried again and saw the issue again (and raised this
bug). However, I have tried to reproduce it again this morning but 2
stack/unstack.sh have completed successfully - where success means no
kernel oops. Each installation of OpenStack is done from a freshly
installed cloud image so perhaps there have been other changes in that
image since Monday/Tuesday this week.
