Date: Mon, 1 Sep 2008 19:41:54 -0700 From: "Justin Mattock" <justinmattock@...il.com> To: "Linux Kernel Mailing List" <linux-kernel@...r.kernel.org> Subject: WARNING: at net/sched/sch_generic.c:221 dev_watchdog+0x125/0x19e() This is probably not a kernel issue but a madwifi issue, but figured I might as well post in both areas. I am running a small test of having one computer act as a shoutcast server with SELinux and ipsec(total lockdown), then another computer act as a costumer with SELinux and ipsec both with AH and ESP encryption; Everything looks good both boxes are sending and receiving AH and ESP encryption without any problems, except for a warning:(below) [ 748.994148] NETDEV WATCHDOG: wifi0 (ath_pci): transmit timed out [ 749.000092] ------------[ cut here ]------------ [ 749.000097] WARNING: at net/sched/sch_generic.c:221 dev_watchdog+0x125/0x19e() [ 749.000101] Modules linked in: ipcomp xfrm_ipcomp btusb cpufreq_ondemand cpufreq_performance cpufreq_powersave rfcomm hidp l2cap bluetooth fan battery authenc esp4 aead ah4 xfrm4_mode_transport des_generic cbc sha1_generic hmac crypto_hash crypto_null ipmi_watchdog ipmi_msghandler uvcvideo uinput wlan_tkip ieee80211_crypt_tkip ieee80211 ieee80211_crypt arpt_mangle arptable_filter arp_tables nf_conntrack_ipv4 nf_conntrack iptable_mangle iptable_filter ip_tables x_tables coretemp eeprom acpi_cpufreq applesmc joydev isight_firmware firewire_ohci firewire_core wlan_scan_sta snd_hda_intel appletouch ath_rate_sample fglrx(P) snd_pcm ohci1394 video ath_pci snd_timer thermal wlan snd_page_alloc ieee1394 snd_hwdep processor ac ath_hal(P) agpgart ehci_hcd uhci_hcd pata_acpi sbshc button evdev [ 749.000220] Pid: 4, comm: ksoftirqd/0 Tainted: P 2.6.27-rc5-00006-gbef69ea #14 [ 749.000226] [<c0123842>] warn_on_slowpath+0x41/0x65 [ 749.000237] [<c021bfc1>] ? _raw_spin_lock+0x53/0xd8 [ 749.000246] [<c021bf6a>] ? _raw_spin_unlock+0x74/0x78 [ 749.000256] [<f8d27e7e>] ? ath_reset+0x335/0x392 [ath_pci] [ 749.000277] [<f8d2841b>] ? ath_tx_timeout+0xbc/0xd5 [ath_pci] [ 749.000295] [<c012422c>] ? printk+0x15/0x17 [ 749.000303] [<c0320c25>] dev_watchdog+0x125/0x19e [ 749.000310] [<c021bf6a>] ? _raw_spin_unlock+0x74/0x78 [ 749.000318] [<c039bd37>] ? _spin_unlock_irq+0x8/0x14 [ 749.000327] [<c011e41d>] ? finish_task_switch+0x32/0x81 [ 749.000335] [<c021bf6a>] ? _raw_spin_unlock+0x74/0x78 [ 749.000342] [<c012aad8>] run_timer_softirq+0x11e/0x180 [ 749.000349] [<c0320b00>] ? dev_watchdog+0x0/0x19e [ 749.000357] [<c0320b00>] ? dev_watchdog+0x0/0x19e [ 749.000365] [<c01273c4>] __do_softirq+0x6d/0xdf [ 749.000372] [<c01275bf>] ? ksoftirqd+0x0/0xaa [ 749.000379] [<c012747e>] do_softirq+0x48/0x57 [ 749.000386] [<c0127605>] ksoftirqd+0x46/0xaa [ 749.000392] [<c0133453>] kthread+0x3b/0x64 [ 749.000399] [<c0133418>] ? kthread+0x0/0x64 [ 749.000406] [<c0103cbf>] kernel_thread_helper+0x7/0x10 [ 749.000414] ======================= [ 749.000418] ---[ end trace 3da383d73b29b600 ]--- At first I was having internet connection, and then a few minutes later nothing, but realized it was ipcomp that I didn't load. When this error occurs the music is streaming, then cuts out for a few seconds, and then back to streaming music. In any case could be madwifi, could be the kernel, better to send a post, than ignore it. regards; -- Justin P.
