Good version

After updating ModemManager, I can no longer use the modem, as it hangs and can only get back to life unplugging it and plugging it again.

The problem has been introduced in commit dc89c0 ("huawei: rework probing and detection")

I'll attach two logfiles of modem-manager --debug

This bug was filled originally in debian, at http://bugs.debian.org/626712

Forgot to mention, as it has been a while since I reported the bug in debian, I have tried again with git HEAD, and it hasn't been fixed yet.

It worked with the previous commit. I tried reverting dc89c0, but I don't know how to resolve the conflicts.

Hi Aleksander.

What is the status of this bug?
Comment 9 Aleksander Morgado 2012-01-15 14:46:59 UTC
Commented the bug in the upstream ML:
http://mail.gnome.org/archives/networkmanager-list/2012-January/msg00020.html

Need to decide whether we revert the commit temporarily or try to find a better solution.
Comment 10 Bartosz 2012-03-09 22:34:13 UTC
According to:
"Next MM 0.5 stable release will come with commit dc89c0 reverted; the latest patch with the ports improvements will come later in master/0.6."
https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/868034/comments/151

Is it possible to close this bug now?


I tested modemmanager 0.5.1.97~0ubuntu1 on Ubuntu Precise Beta (12.04), and it works much better after revert the commit dc89c0 (Revert "huawei: rework probing and detection"). More information:

Comment 11 Aleksander Morgado 2012-03-10 17:37:15 UTC
Yes, we can resolve it as fixed now. As you say, the stable MM 0.5 comes with the patch reverted, and the new ports improvements are already available in git master and in the 06-api branch,

This problem has been fixed in our software repository. The fix will go into the next software release. Thank you for your bug report.
