Description of problem:
My Huawei E220 modem USED to work on Fedora 12. I am not sure at what point in time this changed, but it was probably in the early part of 2010. In the past, I could click on the defined connection in Network Manager and the E220 would connect to the 3G network without any problems.

Now, Network Manager still sees the modem and I can add a new connection, but when I click to connect, /var/log/messages show it connects and immediately disconnects with a "reason 36".

If I use an XP guest on Virtualbox on the Fedora 12 Host on the same notebook, it works. Also, I can make it connect using wvdial.  So the modem is working on the notebook, but NetworkManager is unable to make it connect.

On my home PC, also running Fedora 12, I have exactly the same response.  So it is not modem related, and it is not hardware or specific installation related.


Version-Release number of selected component (if applicable):
ModemManager-0.3-9.git20100409.fc12.x86_64
kernel-2.6.32.12-115.fc12.x86_64
NetworkManager-0.8.0-6.git20100408.fc12.x86_64
ppp-2.4.5-8.fc12.x86_64

How reproducible:
Every time!

Steps to Reproduce:
1. Plug in e220 modem and wait for it to register on the 3G network (LED pulses blue)
2. Add a connection with the Wizard (or use an existing one know to have worked before).
3. Open NetworkManager and select my 3G Connection.  
  
Actual results:
For about 0.5 second the green spinning circles appear on the NetworkManager icon.  Simultaneously the Broadband Mobile items disappear from the NetworkManager list, but reappear after about 10 seconds.  The connection was never established.  /var/log/messages shows the error as "Reason 36".

Expected results:
It should connect to the Broadband Mobile network.

Additional info:
The signal strength of the connection is not shown at all.

According to comment #2, modem-manager goes to infinite loops and crashes.
I'm not quite sure, but it could be caused by this commit:
http://cgit.freedesktop.org/ModemManager/ModemManager/commit/?id=49c363d83af84021f74f04c8141313d21e75821b

See the patch in the attachment.
Comment 6 Louis van Dyk 2010-06-19 17:52:55 UTC 
Hi Jirka

I have looked at this and have NO idea on how to apply the fix.  Do I need the src or the devel package?  How do I apply the diff?  Is there a HOWTO you can point me to?

I have installed Fedora 13 on another PC and it still has the same fault.

Any pointers will be welcome.

Thanks
Louis
Comment 7 Dan Williams 2010-06-22 09:00:49 UTC 
I've pushed jklimes' fix and will roll that into an MM update shortly so we can figure out if it fixes the crash or not.
Comment 8 Dan Williams 2010-06-22 09:22:41 UTC 
I've built a scratch package here: if you could grab the packages from here relevant to your architecture (x86_64 or i686) and see if they fix the problem, that would be great.  Thanks!

http://koji.fedoraproject.org/koji/taskinfo?taskID=2264691

(click on the appropriate "Descendent Tasks" for your architecture and grab the packages in the links at the bottom of the Descendent Task page).  You really only need the ModemManager RPM, not the .src.rpm or the debuginfo RPM.
Comment 9 Louis van Dyk 2010-06-22 12:20:41 UTC 
Thanks, but sadly this did not work.

The RPM used was: ModemManager-0.4-1.git20100622.fc13.x86_64.rpm  

I have uploaded an attachment with my results: the /var/log/messages file and the output of lsusb -v.

Please let me know what else I can do to assist in solving this.

Regards
Louis

/var/log/messages and lsusb -v output

Results in response to Dan's request to test of 22 June 2010.
Comment 11 Dan Williams 2010-06-22 18:20:34 UTC 
Ok, thanks for testing.  One more thing.  Let's try to get a backtrace from modem-manager when it dies.  Here's what you do:

1) start with the device unplugged
2) grab the -debuginfo RPM from the koji link above and install it.  This will give us much more useful backtraces.
3) mv /usr/sbin/modem-manager /
4) killall -TERM modem-manager
5) gdb /modem-manager
6) at the "(gdb)" prompt type "run --debug" and hit return
7) now plug your modem in and reproduce the problem
8) watch the "gdb" window, when MM crashes you'll see it return to the (gdb) prompt at the bottom of the window and it'll say something like "received SIGSEGV".
9) now type "t a a bt" (thread apply all backtrace) and hit return, it may spit out a few pages of output, and you might need to hit Return a few times when GDB asks you to do so.  Copy & paste that into this bug report so I can figure out what's going wrong.

Thanks!
Comment 12 Louis van Dyk 2010-06-22 23:22:32 UTC 
Hi Dan

Not too many lines, and nothing after entering the t a a bt.  So here is the output.

It asked more more debug packages.  Do you need another run with all of those?

Thanks for your efforts!!

Updated modem-manager didn't crash (so no backtrace on 't a a bt'). So it fixes the issue from comment #2.

It appears there is another issue.

These lines from the output suggest kernel driver problem.
Louis, could you check your firmware version as described here:
https://bugzilla.kernel.org/show_bug.cgi?id=14499#c35

Comment 14 Louis van Dyk 2010-06-23 15:57:51 UTC 
It took a long time to update the status, but:

AT+GCAP
Manufacturer: huawei
Model: E220
Revision: 11.117.10.00.00

COMMAND NOT SUPPORT

+GCAP: +CGSM,+DS,+ES

OK

OK

According to the link you quoted, the minimum working firmware version for the Huawei E220 is 11.117.09.04.00, so I have a later version than that.

Also, reading through the posts reminded me that if I use a wvdial script it DOES connect, so I don't think the firmware is the problem.

Comment 15 Louis van Dyk 2010-06-24 17:32:08 UTC 
Further to the firmware question ... using a friend's E226 (see details below) I experience EXACTLY the same problem.  Same errors in /var/log/messages and also can dial using wvdial script.  But I need it to work in Network Manager!

Bump
Comment 17 Dan Williams 2010-06-28 19:17:28 UTC 
With the new ModemManager that no longer crashes, is there any chance you could post the full modem-manager --debug log from a connection attempt with NetworkManager?  I'd like to get a fresh log:

1) start with the device unplugged
2) service NetworkManager stop
3) killall -TERM modem-manager
4) modem-manager --debug
5) NM_PPP_DEBUG=1 NetworkManager --no-daemon --log-level=debug

then try to connect to the network, and attach the modem-manager and NetworkManager logs to the report so we can figure out what's going on now that MM doesn't crash.  Thansk!

Comment 23 Jirka Klimes 2010-07-20 09:29:05 UTC 
Do you see some errors in dmesg?

Looks like modem-manager quits. Both in comment #12 and comment #19, the last trace is 'AT+CSQ'. Do you see any weirdness when running the command via minicom?

It would be nice to have call trace from modem-manager to see the last function. Would you mind do run steps in comment #17 again, but now with step 4) like this:
4) callgraph /usr/sbin/modem-manager --debug

You get callgraph script here:
wget http://superadditive.com/software/callgraph.tar.gz

(It runs program using gdb to trace called functions.)

yunus; the problems you're having here are not related to the original bug; could you file a new one please for your specific issue?
Comment 27 Dan Williams 2010-07-20 17:44:37 UTC 
Aha, I just fixed the issue in comment #12, which is because the modem reports an invalid carrier string FFFFFFFFFFFFFFFF which for various reasons we sometimes need to decode from a hexadecimal string into a UTF-8 string.  And error in ModemManager was incorrectly decoding that string (which in this case isn't valid anyway) and MM tried to send invalid UTF-8 through D-Bus, which then terminates ModemManager.
