I ran a yum provides query and then went back to my xchat session while I waited for that to process. Package: kernel Architecture: i686 OS Release: Fedora release 17 (Beefy Miracle)
Arend and/or Stanislaw, do you have any ideas about why this WARNING still happens? Did I misdiagnose it in comment 1?
Created attachment 580390 [details] brcmsmac: dmesg output of backtrace I see the same warning+crash with the same driver on F17 Beta (kernel 3.3.2-8.fc17.x86_64), also a HP notebook (HP 625, to be exact; I can provide a smolt link). The problem is related to pairing via bluetooth. Bluetooth and Wifi are hardwired/connected in this device, it appears. The bluetooth connection only holds a few seconds, afterwards I see this dmesg output. Sometimes the bluetooth-applet is in an inconsistens state. The computer had SUSE Enterprise preinstalled where paring and BT audio worked flawlessly. Unfortunately, I don't know any software+kernel version numbers. Anything else I can do to help/debug? Would be great to see this fixed in F17 final.
Thinking about it, I'm rather sure now that the SUSE system used the non-free broadcom-wl driver so the results aren't really comparable. With bluetooth-wl, bluetooth connections are still non-working so my above comment is rather misleading. The warning/crash however did happen in connection with a BT connection attempt.
The message can also occur with regulatory domain including channels 12 and 13. Another patch is in upstream kernel: brcm80211: smac: resume transmit fifo upon receiving frames There have been reports about not being able to use access-points on channel 12 and 13 or having connectivity issues when these channels were part of the selected regulatory domain. Upon switching to these channels the brcmsmac driver suspends the transmit dma fifos. This patch resumes them upon handing over the first received beacon to mac80211.
F17 test kernels w/ the patch mentioned in comment 8 are building here: http://koji.fedoraproject.org/koji/taskinfo?taskID=4026143 When they finish building, please give them a try and post the results here -- thanks!

Thanks
I updated the F17-beta install with Kernel-3.3.4-4fc17.i686. Still unable to connect to any access point using the BRCM-4313 interface. It does not matter if I try WEP, WPA or WPA2. I wish I had bought an intel machine with intel wireless instead.
still in 3.3.7-1.fc17.i686
Still in F17 final both x86_64 and 686. My laptop is Samsung NP305U1A Indian edition. I can run any specific code or otherwise help in getting this going.

Sorry to chime in with a near identical post to the one just above, but this has gotten even worse and much more frequent in the past few weeks. It's been getting worse with every kernel update. [tod@Shirokuro ~]$ uname -a Linux Shirokuro 3.6.7-1-ARCH #1 SMP PREEMPT Sun Nov 18 10:11:22 CET 2012 x86_64 GNU/Linux It's really strange that I get a message about Bluetooth during the errors, and after my connection drops. I get the connection working again as you can see at the end, by restarting dhcpcd and net-auto-wireless (part of Arch's netcfg). Also, sorry for the semi-long dmesg: [ 172.407869] wlan0: associated [ 172.407951] cfg80211: Calling CRDA for country: US [ 172.413603] cfg80211: Regulatory domain changed to country: US [ 172.413607] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 172.413610] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2700 mBm) [ 172.413612] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 1700 mBm) [ 172.413614] cfg80211: (5250000 KHz - 5330000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 172.413616] cfg80211: (5490000 KHz - 5600000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 172.413618] cfg80211: (5650000 KHz - 5710000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 172.413620] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 3000 mBm) [ 179.333210] ieee80211 phy0: brcms_ops_bss_info_changed: arp filtering: enabled true, count 1 (implement) [ 1653.565113] Bluetooth: Core ver 2.16 [ 1653.565149] NET: Registered protocol family 31 [ 1653.565152] Bluetooth: HCI device and connection manager initialized [ 1653.565155] Bluetooth: HCI socket layer initialized [ 1653.565158] Bluetooth: L2CAP socket layer initialized [ 1653.565178] Bluetooth: SCO socket layer initialized [ 1653.569464] Netfilter messages via NETLINK v0.30.
