[Bug 1269405] Re: Kernel Panic when 'telinit u', or (re)installing packages

[James Hunt]

I cannot recreate this issue on either 32-bit or 64-bit fully-updated
trusty systems. What would be useful is to know if it also affects the
Session Init (upstart running as the user) since that would allow debug
to be collected without the kernel panicking.

To find out, please can those affected boot to a *desktop* and run the
following as a non-root user:

$ get_state.sh | json_pp > upstart.state
$ start re-exec

Then, attach the following to this bug if a crash results:

$HOME/.xsession-errors
$HOME/.cache/upstart/upstart.state

If the Session Init does crash, we might be lucky and get a crash file
in /var/crash/.
