[Bug 1638270] [NEW] carkit bluetooth reboots ubuntu touch on Nexus4 when switched on/off a couple of times

[David Kaplan]

Public bug reported:

My bluetooth car hands free system reboots my Nexus4 phone when set to auto reconnect and then the ignition switch is turned on and off a couple of times. The carkit is recognized as "comf_comp_V12b".
I am using the Aquarius image (though it previously occurs with the standard Nexus4 image). I am dual booting with Android.
 What other information can I give to help find the problem?
Thanks
