[abrt] crash in ModemManager-0.3-11.git20100502.fc12: Process /usr/sbin/modem-manager was killed by signal 11 (SIGSEGV)
Last modified: 2010-12-03 09:45:30 EST
abrt 1.0.9 detected a crash. architecture: x86_64 Attached file: backtrace cmdline: /usr/sbin/modem-manager component: ModemManager executable: /usr/sbin/modem-manager global_uuid: 456d25779e6948de4c7b7fe87498e0fd1998af9f kernel: 2.6.32.11-99.fc12.x86_64 package: ModemManager-0.3-11.git20100502.fc12 rating: 3 reason: Process /usr/sbin/modem-manager was killed by signal 11 (SIGSEGV) release: Fedora release 12 (Constantine) comment ----- Still not working :-( Tried usb_modeswitch which isn't needed for this modem...
Created attachment 413582 [details] File: backtrace
Is this crash easily reproducible? Does it happen when you remove the modem? Or at some other time?
It seems to happen when the USB modem is disturbed and disconnects from the provider. I believe it recovers once successfully but throws this signal on the 2nd occurrence(?)
This may be related: the modem starts reporting "kernel: option: option_instat_callback: error -84" repeatedly.
What kind of modem is this? 'lsusb' would be useful here. It appears the option driver may need some workarounds to cope with this modem. Also, could you try the following? yum install gdb debuginfo-install ModemManager service NetworkManager stop killall -TERM modem-manager gdb modem-manager r --debug (and in another root terminal do:) service NetworkManager start and then try to reproduce the problem; when the crash happens you'll see 'gdb' stop modem-manager and drop you to the (gdb) prompt in that terminal. Then, type 'backtrace' to get a better stacktrace of what's going on in modem-manager. Let me know if you need more details on this procedure. Thanks!
Possibly related to Bug 589798? I am updating to the 0.3-13.git20100507.fc12 version and following your steps... From lsusb: ID 1410:2110 Novatel Wireless Ovation U720/MCD3000. It is actually a USB720.
Also (for others viewing this bug), since this package is in testing, I needed "debuginfo-install --enablerepo=updates-testing ModemManager"

This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
