Description of problem: I get the following kernel traceback in my logs when I boot my fedora 16 system. It looks similar to other bugs I see in the database on fedora 15 with different NICs and different kernels, but it seems different enough to go ahead and report separately: Nov 19 22:41:55 zooty kernel: [ 10.921250] atl1c 0000:06:00.0: atl1c: p6p1 NIC Link is Up<1000 Mbps Full Duplex> Nov 19 22:41:55 zooty kernel: [ 10.921723] ADDRCONF(NETDEV_CHANGE): p6p1: link becomes ready Nov 19 22:41:55 zooty kernel: [ 10.921795] br0: port 1(p6p1) entering forwarding state Nov 19 22:41:55 zooty kernel: [ 10.921799] br0: port 1(p6p1) entering forwarding state Nov 19 22:41:55 zooty kernel: [ 10.922431] ADDRCONF(NETDEV_CHANGE): br0: link becomes ready Nov 19 22:41:56 zooty ntpd[884]: Listen normally on 4 br0 192.168.1.106 UDP 123 Nov 19 22:41:56 zooty ntpd[884]: peers refreshed Nov 19 22:41:56 zooty kernel: [ 11.835521] atl1c 0000:06:00.0: atl1c: p6p1 NIC Link is Down Nov 19 22:41:56 zooty kernel: [ 11.918788] br0: port 1(p6p1) entering forwarding state Nov 19 22:41:59 zooty ntpd[884]: Listen normally on 5 br0 fe80::16da:e9ff:fe72:9e22 UDP 123 Nov 19 22:41:59 zooty ntpd[884]: Listen normally on 6 p6p1 fe80::16da:e9ff:fe72:9e22 UDP 123 Nov 19 22:41:59 zooty ntpd[884]: peers refreshed Nov 19 22:41:59 zooty kernel: [ 14.851899] atl1c 0000:06:00.0: atl1c: p6p1 NIC Link is Up<1000 Mbps Full Duplex> Nov 19 22:41:59 zooty kernel: [ 14.852368] br0: port 1(p6p1) entering forwarding state Nov 19 22:41:59 zooty kernel: [ 14.852374] br0: port 1(p6p1) entering forwarding state Nov 19 22:42:04 zooty kernel: [ 19.897852] ------------[ cut here ]------------ Nov 19 22:42:04 zooty kernel: [ 19.897860] WARNING: at net/sched/sch_generic.c:255 dev_watchdog+0xf0/0x150() Nov 19 22:42:04 zooty kernel: [ 19.897862] Hardware name: System Product Name Nov 19 22:42:04 zooty kernel: [ 19.897863] NETDEV WATCHDOG: p6p1 (atl1c): transmit queue 0 timed out Nov 19 22:42:04 zooty kernel: [ 19.897865] Modules linked in: ppdev parport_pc lp parport bridge stp llc w83627ehf hwmon_vid coretemp ip6t_REJECT nf_conntrack_ipv6 nf_defrag_ipv6 ip6table_filter ip6_tables nf_conntrack_ipv4 nf_defrag_ipv4 xt_state nf_conntrack snd_hda_codec_hdmi snd_hda_codec_realtek joydev usblp usb_storage uas eeepc_wmi asus_wmi sparse_keymap rfkill snd_hda_intel snd_hda_codec snd_hwdep snd_seq snd_seq_device snd_pcm virtio_net kvm_intel microcode kvm serio_raw i2c_i801 iTCO_wdt atl1c iTCO_vendor_support snd_timer snd soundcore snd_page_alloc uinput nfsd lockd nfs_acl auth_rpcgss sunrpc wmi i915 drm_kms_helper drm i2c_algo_bit i2c_core video [last unloaded: scsi_wait_scan] Nov 19 22:42:04 zooty kernel: [ 19.897902] Pid: 0, comm: swapper Not tainted 3.1.1-2.fc16.x86_64 #1 Nov 19 22:42:04 zooty kernel: [ 19.897904] Call Trace: Nov 19 22:42:04 zooty kernel: [ 19.897905] <IRQ> [<ffffffff81057a1e>] warn_slowpath_common+0x83/0x9b Nov 19 22:42:04 zooty kernel: [ 19.897911] [<ffffffff81057ad9>] warn_slowpath_fmt+0x46/0x48 Nov 19 22:42:04 zooty kernel: [ 19.897914] [<ffffffff813f0945>] ?
