Description of problem: I have an iwl3945 wireless card that, for the most part, works great with Linux and NetworkManager and so on. Recently, though -- unfortunately I don't know how long -- when I have my laptop plugged into the network at work, the wireless card is emitting a constant stream of messages. In /var/log/messages, it looks like this: Jan 28 09:05:40 floopy NetworkManager: <info> Trying to start the supplicant... Jan 28 09:05:40 floopy NetworkManager: <info> (eth0) supplicant interface is now in state 1 (from 0). Jan 28 09:05:40 floopy NetworkManager: <info> (wlan0) supplicant manager is now in state 1 (from 0). Jan 28 09:05:40 floopy NetworkManager: <info> (eth0) supplicant interface is now in state 2 (from 1). Jan 28 09:05:40 floopy NetworkManager: <info> (wlan0) supplicant interface is now in state 2 (from 1). Jan 28 09:06:00 floopy kernel: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready Jan 28 09:06:05 floopy kernel: printk: 2 messages suppressed.

Jan 28 09:06:25 floopy kernel: printk: 64 messages suppressed. [ ... ] In the output of dmesg, there's a bit more information: wlan0: RX non-WEP frame, but expected encryption printk: 42 messages suppressed. wlan0: RX non-WEP frame, but expected encryption printk: 71 messages suppressed. wlan0: RX non-WEP frame, but expected encryption printk: 138 messages suppressed. wlan0: RX non-WEP frame, but expected encryption printk: 109 messages suppressed. wlan0: RX non-WEP frame, but expected encryption eth0: no IPv6 routers present printk: 60 messages suppressed. wlan0: RX non-WEP frame, but expected encryption printk: 64 messages suppressed. [ ... ] This flood of messages stops as soon as I disable wireless through NetworkManager. It only happens at work, where there are a couple of wireless networks that I don't use; wireless works great at home and other places that I've used it. Version-Release number of selected component (if applicable): kernel-2.6.23.14-115.fc8 (but it's been happening for a while) How reproducible: Always Steps to Reproduce: 1. Boot computer at work with NetworkManager enabled 2. Connect to wired network Actual results: Constant flood of kernel errors until I disable wireless Expected results: Wireless to shut up because I'm not even using it! :)
One additional note: it seems that this problem *may* have started when I installed NetworkManager-0.7.0-0.6.7.svn3204. Since I can stop the problem from happening by disabling wireless in NM, I'm reassigning the bug (sorry for the churn).
Thoughts John? Shouldn't be spewing messages, but I'm unclear of what sort of frames mac80211 is expecting here that would cause it to output the message. NM should not be touching the wireless device at all (in the version the reporter mentions there is no multiple active device support) but perhaps an 'iwconfig wlan0' would be useful here.
NB: I've been away from this particular location for a couple of months. But I'm now back here, and the message spew is still happening. If you need me to test anything, I'm willing.
The build here has a patch that removes the message in question: http://koji.fedoraproject.org/koji/buildinfo?buildID=46311 When the build complete, could you give it a try and confirm that the message is gone? Thanks!
I'll try the build shortly (need to reboot). For now, here's the output of /sbin/iwconfig wlan0 under the current kernel (while the messages are spewing into the log): wlan0 IEEE 802.11 ESSID:"central" Mode:Managed Frequency:2.437 GHz Access Point: 00:16:35:9D:4B:F3 Bit Rate=54 Mb/s Tx-Power=15 dBm Retry min limit:7 RTS thr:off Fragment thr=2352 B Encryption key:off Link Quality=80/100 Signal level=-54 dBm Noise level=-41 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 "central" is the wireless network that I'm not actually using. I have connected to it in the past, I think, but these days I'm always plugged into eth0 and that's what I actually use. If I disable wireless in NM, iwconfig produces the following: wlan0 IEEE 802.11 ESSID:"central" Mode:Managed Frequency:2.437 GHz Access Point: Not-Associated Tx-Power=15 dBm Retry min limit:7 RTS thr:off Fragment thr=2352 B Encryption key:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0

Thanks! Yes, the message is indeed gone with this kernel. Yay! :)
