Re: [Bug 476621] Re: ModemManager segfaults with Sierra AirCard 880

I've set up /etc/ppp/peers/provider to use my Sierra Aircard. Works
fine via command line.

[Bug 476621] Re: ModemManager segfaults with Sierra AirCard 880

[Bruce Wolfe]

Hi Patrick,

I have set up the launchpad ppa and updated to the most recent as at Aust EDT 
20 Nov 2009 6pm.
I have compiled and installed the latest kernel module from Sierra 1.7.2 with 
debug turned on. Rebooted to be absolutely sure and then tried again.

Still not working!

Attached is the syslog covering most (I think) of the relevant output.

Let me know if I can do anything else - although I am travelling a fair
amount at the moment so difficult to find appropriate opportunities to
work on this.

Having to work through my Windows partition for 3G at the moment - very
depressing.

Regards
Bruce

Does the problem persist with the current nightly build from

I have a similar issue - although I am using an embedded Sierra MC8780
card.

Happy to test or provide additional details.

Modem Manager is segfault every time I try to connect ... (Latest syslog
