no cellular connection and settings

[dinamic]

no cellular connection and settings (arale/rc-proposed)
i have no idea how to reproduce this bug but it already happened 3 times to me, the cellular icon (indicator) is gone and also the the "Cellular" entry from System Settings/Network (see screenshot). when it happens i can't dial or receive calls. the most annoying thing is that i am not allays aware that i don't have cell connection since the only giveaway is the missing cell icon.

workaround, restart phone

Thanks for your report. Could you reproduce it and attach /var/log/syslog to this bug report?

[dinamic (dinamic6661)]

syslog attached, but i have no idea how to reproduce this bug

Not really much is seeing in the syslog. Was there any file in /var/crash ?

I noticed the same recently on my mako under rc-proposed.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[dinamic (dinamic6661)]

and it happened again (arale/rc - pre ota 12). i think it's now the 4th time since i see this happening and i have no idea why and how to debug it

[Alfonso Sanchez-Beato (alfonsosanchezbeato)]

@dinamic, please attach syslog again. Also, the output of running:

/usr/share/ofono/scripts/list-modems
/usr/share/ofono/scripts/list-context

when this is happening would be useful.

[dinamic (dinamic6661)]
