bug report - samsung n150 netbook - after update not able to connect 3G broadband + debug

[Daniel Duris <dusoft gmail com>]

I am reporting bug - after update of Ubuntu Mint, 3g modem is unable
to connect. SIM card is correctly connected I can assure you despite
the message from the network manager. as no chabnge to the sim card
has been done. only change is complete update of ubuntu mint. same
error (unable to connect) happens for multiple SIM card from different
providers and multiple distributions (xubuntu tested as well).

so this is definitely some bug in networkmanager used by the both
systems i suppose.

uname -a output:
Linux sumo 2.6.35-22 generic #35-Ubuntu SMP ............ i686 GNU/Linux


complete DEBUG showing the bug and making computer totally useless for
3G connections:
