From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ben Greear Subject: igb: 2.6.34.1: kernel warning at igb_main.c:2080 Date: Thu, 15 Jul 2010 16:56:46 -0700 Message-ID: <4C3FA03E.9090802@candelatech.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit To: NetDev Return-path: Received: from mail.candelatech.com ([208.74.158.172]:44609 "EHLO ns3.lanforge.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S934004Ab0GOX4r (ORCPT ); Thu, 15 Jul 2010 19:56:47 -0400 Received: from [192.168.100.195] (firewall.candelatech.com [70.89.124.249]) (authenticated bits=0) by ns3.lanforge.com (8.14.2/8.14.2) with ESMTP id o6FNukQA004984 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NO) for ; Thu, 15 Jul 2010 16:56:46 -0700 Sender: netdev-owner@vger.kernel.org List-ID: We just saw this kernel warning on 2.6.34.1 + a few patches from the pending stable queue, plus our own hacks (though none to igb). We were running a modified version of pktgen traffic and at the same time bounced the port. This warning didn't seem to cause any real problems. Please let us know if you would like any additional information. ]# lspci|grep Ethern 01:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection 02:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection 05:00.0 Ethernet controller: Intel Corporation 82575EB Gigabit Network Connection (rev 02) 05:00.1 Ethernet controller: Intel Corporation 82575EB Gigabit Network Connection (rev 02) 06:00.0 Ethernet controller: Intel Corporation 82575EB Gigabit Network Connection (rev 02) 06:00.1 Ethernet controller: Intel Corporation 82575EB Gigabit Network Connection (rev 02) Jul 15 16:36:01 localhost kernel: ------------[ cut here ]------------ Jul 15 16:36:01 localhost kernel: WARNING: at /home/greearb/git/linux-2.6.dev.34.y/drivers/net/igb/igb_main.c:2080 igb_close+0x28/0x9f [igb]() Jul 15 16:36:01 localhost kernel: Hardware name: X8STi Jul 15 16:36:01 localhost kernel: Modules linked in: bridge arc4 michael_mic wanlink(P) 8021q garp xt_CT iptable_raw ipt_addrtype xt_DSCP xt_dscp xt_string xt_owner xt_NFQUEUE xt_multiport xt_mark xt_iprange xt_hashlimit xt_CONNMARK xt_connmark stp llc veth fuse macvlan bpctl_mod pktgen iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi nfs lockd fscache nfs_acl auth_rpcgss sunrpc ipv6 dm_multipath uinput i2c_i801 iTCO_wdt i2c_core ioatdma e1000e igb pcspkr iTCO_vendor_support dca ata_generic pata_acpi [last unloaded: nf_nat] Jul 15 16:36:01 localhost kernel: Pid: 17516, comm: ip Tainted: P 2.6.34.1 #2 Jul 15 16:36:01 localhost kernel: Call Trace: Jul 15 16:36:01 localhost kernel: [] ? igb_close+0x28/0x9f [igb] Jul 15 16:36:01 localhost kernel: [] warn_slowpath_common+0x77/0x8f Jul 15 16:36:01 localhost kernel: [] warn_slowpath_null+0xf/0x11 Jul 15 16:36:01 localhost kernel: [] igb_close+0x28/0x9f [igb] Jul 15 16:36:01 localhost kernel: [] __dev_close+0x73/0x86 Jul 15 16:36:01 localhost kernel: [] __dev_change_flags+0xa8/0x12b Jul 15 16:36:01 localhost kernel: [] dev_change_flags+0x1c/0x51 Jul 15 16:36:01 localhost kernel: [] do_setlink+0x273/0x482 Jul 15 16:36:01 localhost kernel: [] ? zone_statistics+0x5e/0x63 Jul 15 16:36:01 localhost kernel: [] rtnl_newlink+0x26c/0x422 Jul 15 16:36:01 localhost kernel: [] ? nla_nest_start+0x1d/0x31 Jul 15 16:36:01 localhost kernel: [] ? virt_to_head_page+0x9/0x2a Jul 15 16:36:01 localhost kernel: [] ? __mutex_lock_common+0x38e/0x3ac Jul 15 16:36:01 localhost kernel: [] rtnetlink_rcv_msg+0x1d9/0x1f7 Jul 15 16:36:01 localhost kernel: [] ? rtnetlink_rcv_msg+0x0/0x1f7 Jul 15 16:36:01 localhost kernel: [] netlink_rcv_skb+0x3e/0x8e Jul 15 16:36:01 localhost kernel: [] rtnetlink_rcv+0x20/0x29 Jul 15 16:36:01 localhost kernel: [] netlink_unicast+0xea/0x151 Jul 15 16:36:01 localhost kernel: [] ? memcpy_fromiovec+0x42/0x73 Jul 15 16:36:01 localhost kernel: [] netlink_sendmsg+0x242/0x255 Jul 15 16:36:01 localhost kernel: [] ? __sock_recvmsg_nosec+0x29/0x2b Jul 15 16:36:01 localhost kernel: [] __sock_sendmsg+0x56/0x5f Jul 15 16:36:01 localhost kernel: [] sock_sendmsg+0xa3/0xbc Jul 15 16:36:01 localhost kernel: [] ? copy_from_user+0x28/0x30 Jul 15 16:36:01 localhost kernel: [] ? verify_iovec+0x52/0x95 Jul 15 16:36:01 localhost kernel: [] sys_sendmsg+0x1c6/0x22a Jul 15 16:36:01 localhost kernel: [] ? lru_cache_add_lru+0x38/0x3d Jul 15 16:36:01 localhost kernel: [] ? _raw_spin_unlock+0x2d/0x38 Jul 15 16:36:01 localhost kernel: [] ? spin_unlock+0x9/0xb Jul 15 16:36:01 localhost kernel: [] ? handle_mm_fault+0x6d3/0x6f3 Jul 15 16:36:01 localhost kernel: [] ? __vma_link_rb+0x2b/0x2d Jul 15 16:36:01 localhost kernel: [] ? vma_link+0xcd/0xcf Jul 15 16:36:01 localhost kernel: [] ? fget_light+0x39/0x87 Jul 15 16:36:01 localhost kernel: [] ? audit_syscall_entry+0xfe/0x12a Jul 15 16:36:01 localhost kernel: [] system_call_fastpath+0x16/0x1b Jul 15 16:36:01 localhost kernel: ---[ end trace 75242fae6dbfdf6d ]--- Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
