Description Stephan Ebelt 2010-06-12 08:27:57 UTC 
abrt 1.1.1 detected a crash.

architecture: i686
Attached file: backtrace
cmdline: /usr/sbin/modem-manager
comment:  I suspect that modem-manager has a problem with asking for that PIN. I can make it work by manually entering the PIN with minicom (at-cpin="1111") and restarting modem-manager thereafter.

How to reproduce

modem-manager --debug output

this is the modem-manager --debug output which (most likely) produced this backtrace. I ran it with the Sierra Modem being inactive, ie has no PIN.  After manually entering the PIN it worked.

there was additional output from /var/log/messages posted in bug #597088.
Comment 3 Dan Williams 2010-06-24 16:20:05 UTC 
Should be fixed upstream be:

commit adfe264b67ba28effd3fb8378cbcbe2081f6ed49
Author: Dan Williams <dcbw>
Date:   Tue Jun 22 01:58:54 2010 -0700

    core: ensure claimed ports don't fall back to Generic (rh #597296)

This isn't a dupe of that bug though since that commit doesn't fix rh #597296, but should fix this bug.
Comment 4 Stephan Ebelt 2010-07-28 18:24:16 UTC 
I upgraded ModemManager from updates-testing as was mentioned in bug #597088 to ModemManager-0.4-4.git20100720.fc13.i686. This appears to solve this bug.

I can now boot my system and it comes up with asking for the PIN right after login and the UMTS connection is available in nm-applet.

thanks,
stephan
