Bug Description

Installing ofono-phonesim-autostart makes the ubuntu phone image continually reboot.

This is due to the fact that for some reason, the upstart ofono job isn't properly stopped by ofono-phonesim-autostart, and thus upstart continually tries to start it, eventually hitting the upstart respawn limit.

This then causes our new upstart monitor job to reboot the phone, which continues ad infinitum.

This can be seen by examining syslog, it seems ofonod is already running ( which is expected ) and another instance is trying to be initiated, which fails.

The ofono-phonesim-autostart package's post-install script stops the normal ofono upstart job and then launches ofono outside of upstart with command-line arguments that cause the 'phonesim' ofono driver to be loaded instead of rilmodem. Apparently some change in vivid has caused this script to break on krillin.

I just installed on mako running vidid-proposed #56.

As expected, ofono-phonesim-autostart stops the running ofonod instance, and restarts it such that phonesim is loaded ( vs. rilmodem ).

I'm able to run list-modems ( /usr/share/ofono/scripts/list-modems ) and confirm that phonesim has been loaded/initialized as the 'Manufacturer' property returned is 'MeeGo'.

I checked and didn't see any related crash files in /var/crash, nor did I see any unusual log messages from ofonod in the syslog. So from my point of view, ofono and ofono-phonesim-autostart are both working as expected.

Please re-test and make sure to provide device, channel, and image #.

I tried rebooting ( which is recommended before running autopilot tests ), and everything still looks fine to me.

I can still reproduce the issue.

Device: krillin
Image: #65
Channel: vivid-proposed

I just did the following:
- flashed the latest vivid-proposed
- installed ofono-phonesim-autostart
- rebooted

Same issue here with image #65, channel ubuntu-touch/devel-proposed on krillin.

It doesn't happen on mako/vivid-proposed, or krillin on RTM.

After this happens, the only way to recover is to force the device to power-off with the power button, and then boot into recovery.

I tried this on a desktop and on mako, both work. I unfortunately can't try this in an emulator as that seems to have broken since last week (bug 1413271), and I don't have a krillin so I can't test this there myself.

Indeed phonesim-autostart does that (through the with-ofono-phonesim script):

service ofono stop || true
ofonod -P ril,rildev,stktest $DEBUG_OFONO -n >/etc/ofono/ofono.log 2>&1 &
OFONO_PID=$!

The || true is intended to guard against failure if ofono is already stopped. But that might be the place where things go wrong in krillin, if ofono somehow fails to stop there? If it runs on, then the ofonod invocation in the next line should fail, not the original instance from the upstart job, but maybe there's something funky going on there. Are there any upstart jobs which are krillin specific and mention ofono in any way?

It might be useful to install just ofono-phonesim *without* ofono-phonesim-autostart, and run with-ofono-phonesim through set -x. Check Which of these succeeds/fails, and use upstart-monitor to see what else happens during that time?
