well, it just looks like NM tries to restart nscd in certain cases (like when the network goes down). I doubt it's the *cause*. The use of 'condrestart' implies that it's only an 'optional' thing and it failing shouldn't be an issue. What it should be doing now is 'systemctl try-restart nscd.service' , but I doubt fixing that would fix your network. Can you attach *all* NM logs - something like 'grep NetworkManager /var/log/messages' ? Thanks. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers Well ok, /var/log/messages is empty and I am not sure if syslogd is running: ps ax | grep syslog 361 ? Ss 0:00 /lib/systemd/systemd-kmsg-syslogd 372 ? Ss 0:00 /lib/systemd/systemd-stdout-syslog-bridge 2082 pts/0 S+ 0:00 grep syslog I attach the output of dmesg grepped for NetworkManager. Hope this helps. Created attachment 530818 [details]
dmesg NetworkManager
"Well ok, /var/log/messages is empty and I am not sure if syslogd is running:" systemctl enable rsyslogd.service well, from the dmesg, it looks like it stays up for 13 minutes, then: [ 805.320176] NetworkManager[681]: NetworkManager[681]: <info> (wlan0): disconnecting for new activation request. But I'm not totally sure why that would happen. I'd more expect that message if you changed APs, or something. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers Ok needed to install rsyslog-sysvinit and started it with chkconfig, since your command refused to work. Didn't think about this possibility since I thought it is already systemd, sorry. Just before dropping the connection I have: Oct 31 07:58:19 caprica systemd[1]: Failed to read PID file /run/sendmail.pid after start. The service might be broken. Don't know if this is also related. Will attach the whole /var/log/messages since before the disconnect there were no NetworkManager related issues. Created attachment 530907 [details]
/var/log/messages
I have the same problem with F15, also with Intel wifi $ lspci | grep Network 00:19.0 Ethernet controller: Intel Corporation 82577LM Gigabit Network Connection (rev 06) 02:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 35) dmesg: [51344.561558] wlan0: deauthenticating from bc:05:43:81:77:02 by local choice (reason=3) [51344.580045] cfg80211: Calling CRDA to update world regulatory domain [51345.039317] cfg80211: World regulatory domain updated: [51345.039322] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [51345.039328] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [51345.039334] cfg80211: (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [51345.039338] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [51345.039343] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [51345.039347] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [51345.039368] cfg80211: Calling CRDA for country: DE [51345.044088] cfg80211: Regulatory domain changed to country: DE [51345.044093] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [51345.044099] cfg80211: (2400000 KHz - 2483500 KHz @ 40000 KHz), (N/A, 2000 mBm) [51345.044103] cfg80211: (5150000 KHz - 5250000 KHz @ 40000 KHz), (N/A, 2000 mBm) [51345.044108] cfg80211: (5250000 KHz - 5350000 KHz @ 40000 KHz), (N/A, 2000 mBm) [51345.044112] cfg80211: (5470000 KHz - 5725000 KHz @ 40000 KHz), (N/A, 2698 mBm) Not sure if this is really NM, but I wonder what "by local choice (reason=3)" is supposed to mean. Probably something related to Intel drivers. Don't know which component or maintainer could help on a driver-related issue, or should we take it rather upstream (intel) in this case? Yeah, that's probably iwlagn driver issue. You can try whether disabling N-mode helps: # rmmod iwlagn # modprobe iwlagn 11n_disable=1 To debug further follow the steps here: http://live.gnome.org/NetworkManager/Debugging#wifi That will enable debug logs from wpa_supplicant Other debugging tips: * http://intellinuxwireless.org/?n=fw_error_report * run 'iw event -f -t' to monitor wireless events Ok, it appears again with the new kernel: 3.2.2-1.fc16.x86_64 I have "disconnects" where for example firefox is not able to load pages but network manager is still connected. Most probably an intel driver issue. 04:00.0 Network controller [0280]: Intel Corporation WiFi Link 5100 [8086:4232] Changed the component to kernel since it's most probably a driver issue. I went back to a previous version of the kernel (3.1.10-2.fc16.x86_64), which doesn't have the problem. hannes, could you test this: https://bugzilla.redhat.com/show_bug.cgi?id=785239#c10 *** This bug has been marked as a duplicate of bug 785239 *** |
