I am running 2.6.36-rc4-wl+, with Johannes's sta_info_get_bss patch, my ath9k rxfilter patch, and Felix's bssid-mask patch. I had created two un-encrypted STA interfaces. I was messing with another machine, trying to get a sniffer working when this happened. I saw this a few days ago as well, but didn't get a chance to get a good stacktrace. kernel BUG at /home/greearb/git/linux.wireless-testing/drivers/net/wireless/ath/ath9k/xmit.c:190! invalid opcode: 0000 [#1] SMP last sysfs file: /sys/devices/pci0000:00/0000:00:1e.0/0000:08:01.0/net/sta1/flags Modules linked in: 8021q garp stp llc fuse michael_mic macvlan pktgen nfs lockd fscache nfs_acl auth_rpcgss sunrpc ipv6 uinput arc4 ecb ath9k mac] Pid: 43, comm: kworker/u:3 Not tainted 2.6.36-rc4-wl+ #1 PDSBM/PDSBM EIP: 0060:[<f8beb313>] EFLAGS: 00010286 CPU: 1 EIP is at ath_tx_start+0x5e2/0x671 [ath9k] EAX: 00000000 EBX: f4b282c0 ECX: f4b282c0 EDX: f67e0054 ESI: 00000004 EDI: 00000000 EBP: f6a15c44 ESP: f6a15c04 DS: 007b ES: 007b FS: 00d8 GS: 0000 SS: 0068 Process kworker/u:3 (pid: 43, ti=f6a14000 task=f7384910 task.ti=f6a14000) Stack: f678d4e0 01880019 f67e007c f67b0004 f4bd582c f678c3e0 00000188 f67d0064 <0> f6a15c6c f678d694 00000000 f67e0054 f67e0054 f678d694 f5a30800 0000001a <0> f6a15c88 f8be5749 f67b0004 00000080 f8bf290b f5a30800 00000002 f678c3e0 Call Trace: [<f8be5749>] ? ath9k_tx+0x223/0x254 [ath9k] [<f8b96b1b>] ? __ieee80211_tx+0xff/0x164 [mac80211] [<f8b97972>] ? ieee80211_tx+0xc1/0x1ad [mac80211] [<f8b97bca>] ? ieee80211_xmit+0x16c/0x179 [mac80211] [<c045629d>] ? trace_hardirqs_on+0xb/0xd [<f8b98ab4>] ? ieee80211_subif_start_xmit+0x62d/0x641 [mac80211] [<c06c540d>] ? rcu_read_unlock+0x17/0x19 [<c06c5977>] ? sock_def_write_space+0xae/0xb3 [<c06d0ec8>] ? dev_hard_start_xmit+0x31b/0x3ed [<c06e1813>] ? sch_direct_xmit+0x50/0x116 [<c06e19b2>] ? __qdisc_run+0xd9/0xf3 [<c06ce37e>] ? net_tx_action+0xb7/0xdf [<c04392e7>] ? __do_softirq+0x86/0x111 [<c04393a8>] ? do_softirq+0x36/0x5a [<c04394e1>] ? irq_exit+0x35/0x68 [<c0418c3a>] ? smp_apic_timer_interrupt+0x6e/0x7c [<c07632ff>] ? apic_timer_interrupt+0x2f/0x40 [<c045007b>] ? do_adjtimex+0x147/0x55e [<c0762b64>] ? _raw_spin_unlock_irqrestore+0x40/0x48 [<f8b9a6c3>] ? ieee80211_wake_queues_by_reason+0x41/0x48 [mac80211] [<f8b9aa1d>] ? ieee80211_wake_queues+0xa/0xc [mac80211] [<f8be510c>] ? ath_reset+0x147/0x159 [ath9k] [<f8be5a11>] ? ath_hw_check+0x3c/0x47 [ath9k] [<c0443c53>] ? process_one_work+0x1bd/0x2c3 [<c0443c09>] ? process_one_work+0x173/0x2c3 [<f8be59d5>] ? ath_hw_check+0x0/0x47 [ath9k] [<c04452fe>] ? worker_thread+0xf7/0x1f7 [<c0445207>] ? worker_thread+0x0/0x1f7 [<c0447cd3>] ? kthread+0x62/0x67 [<c0447c71>] ? kthread+0x0/0x67 [<c0403506>] ? kernel_thread_helper+0x6/0x1a -- Ben Greear <greearb@xxxxxxxxxxxxxxx> Candela Technologies Inc http://www.candelatech.com -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
