Comment 1 Niels Haase 2009-06-22 21:32:10 UTC

Thanks for filling this bug. Can you please try the version NetworkManager-0.7.1-5.git20090617.fc11 in update-testing and see if the problem is still present. The easy way to install it with all possible dependencies resolved is to use the below statement:

If you want to test the update, you can install it with
su -c 'yum --enablerepo=updates-testing update wpa_supplicant NetworkManager
mobile-broadband-provider-info'.

Comment 2 A S Alam 2009-06-25 06:28:07 UTC

problem got more serious with latest package. I got kernel oops with each time
connect to device. with more testing, if used 'wvdial' to connect once, then
afterward, networkmanagar works fine (after disconnect wvdial and connect with NM).

Comment 3 Niels Haase 2009-06-25 07:54:26 UTC

Maybe it a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=500954

With Kernel 2.6.29.3-140.fc11 there are oops with usb 3G modems reported. Do you see the same or similar oppes?
