Linville" <linville@...driver.com>, Brett Rudley <brudley@...adcom.com>, Roland Vossen <rvossen@...adcom.com> Cc: linux-wireless@...r.kernel.org, netdev@...r.kernel.org Subject: assert_cfg80211_lock warning with Linux v3.5-8833-g2d53492 Hi All, With the latest Linus tree as of this morning, I'm getting the warning below continuously. I've attached the first two instances of it. The machine is a Dell XPS 8300 with a BCM4313 wireless chip in it. Userspace is Fedora 17 and NetworkManager is controlling things though I don't have it set to connect to any networks. Please let me know if you've seen this before and if there is more information I can provide. josh [ 15.587855] brcmsmac bcma0:0: mfg 4bf core 812 rev 24 class 0 irq 16 [ 15.636460] cfg80211: World regulatory domain updated: [ 15.636462] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 15.636463] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 15.636465] cfg80211: (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 15.636466] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 15.636467] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 15.636468] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 15.703640] ieee80211 phy0: Selected rate control algorithm 'minstrel_ht' [ 15.957344] ALSA sound/pci/hda/hda_intel.c:2745 Using COMBO position fix [ 15.957532] snd_hda_intel 0000:00:1b.0: irq 46 for MSI/MSI-X [ 16.253325] cfg80211: Calling CRDA for country: US [ 16.271042] cfg80211: Regulatory domain changed to country: US [ 16.271045] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 16.271048] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2700 mBm) [ 16.271051] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 1700 mBm) [ 16.271053] cfg80211: (5250000 KHz - 5330000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 16.271055] cfg80211: (5490000 KHz - 5600000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 16.271057] cfg80211: (5650000 KHz - 5710000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 16.271060] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 3000 mBm) <snip a bunch of ALSA/input stuff> [ 21.762086] nf_conntrack version 0.5.0 (16384 buckets, 65536 max) [ 25.698788] Bridge firewalling registered [ 25.746690] device virbr0-nic entered promiscuous mode [ 26.573028] ------------[ cut here ]------------ [ 26.573042] WARNING: at net/wireless/core.h:125 assert_cfg80211_lock.part.8+0x15/0x17 [cfg80211]() [ 26.573045] Hardware name: XPS 8300 [ 26.573046] Modules linked in: xt_CHECKSUM iptable_mangle bridge stp llc ip6t_REJECT nf_conntrack_ipv4 nf_conntrack_ipv6 nf_defrag_ipv6 nf_defrag_ipv4 xt_state nf_conntrack ib_iser rdma_cm ib_addr ip6table_filter tpm_bios ip6_tables iw_cm ib_cm ib_sa ib_mad ib_core iscsi_tcp snd_hda_codec_hdmi snd_hda_codec_realtek snd_hda_intel arc4 brcmsmac snd_hda_codec cordic brcmutil snd_hwdep mac80211 snd_pcm snd_page_alloc snd_timer cfg80211 snd coretemp rfkill serio_raw i2c_i801 soundcore lpc_ich bcma dcdbas microcode mfd_core mei vhost_net tun macvtap macvlan kvm_intel nfsd kvm auth_rpcgss nfs_acl lockd uinput crc32c_intel ghash_clmulni_intel broadcom tg3 usb_storage uas radeon i2c_algo_bit drm_kms_helper ttm drm i2c_core sunrpc be2iscsi bnx2i cnic uio cxgb4i cxgb4 cxgb3i cxgb3 mdio libcxgbi libiscsi_tcp qla4xxx iscsi_boot_sysfs libiscsi scsi_transport_iscsi [ 26.573143] Pid: 757, comm: NetworkManager Not tainted 3.6.0-0.rc0.git8.1.fc18.x86_64 #1 [ 26.573145] Call Trace: [ 26.573153] [<ffffffff8106782f>] warn_slowpath_common+0x7f/0xc0 [ 26.573159] [<ffffffff8106788a>] warn_slowpath_null+0x1a/0x20 [ 26.573170] [<ffffffffa04c730d>] assert_cfg80211_lock.part.8+0x15/0x17 [cfg80211] [ 26.573181] [<ffffffffa04a8dcb>] freq_reg_info+0x6b/0x80 [cfg80211] [ 26.573193] [<ffffffffa06b6c99>] brcms_c_channel_set_chanspec+0x2c9/0x350 [brcmsmac] [ 26.573204] [<ffffffffa06b7330>] brcms_c_set_phy_chanspec+0x30/0x70 [brcmsmac] [ 26.573216] [<ffffffffa06c1a45>] brcms_c_init+0xb25/0x12f0 [brcmsmac] [ 26.573225] [<ffffffffa047e61c>] ?
