Hi, we are running abount eigth HP Blade servers with the official openvz kernel from the debian repository. On this blades we are faced with a LOT of those messages. This messages are logged in dmesg and also in /var/log/messages.
This hardware is useing the bnx2x chipset. The exactly same setup but running as vmware virtual machine is not logging those messages. The system is running stable but I would like to ask what this messages are kind of? Maybe a combination of bnx2x firmware and vzeth? Regards Mario Output of /var/log/messages: Oct 16 20:20:34 atlxvz30223 kernel: [215041.520059] ------------[ cut here ]------------ Oct 16 20:20:34 atlxvz30223 kernel: [215041.520064] WARNING: at net/core/dev.c:1440 skb_gso_segment+0x88/0x1ae() Oct 16 20:20:34 atlxvz30223 kernel: [215041.520067] Modules linked in: vzethdev vznetdev simfs vzrst vzcpt tun vzdquota vzmon vzdev xt_tcpudp xt_length ipt_ttl xt_tcpmss xt_TCPMSS iptable_mangle iptable_filter xt_multiport xt_limit xt_dscp ipt_REJECT ip_tables x_tables mptctl mptbase sg ipmi_devintf ipv6 bonding loop ipmi_si ipmi_msghandler usbhid hid psmouse hpilo ff_memless snd_pcm serio_raw pcspkr snd_timer snd soundcore snd_page_alloc container button bnx2x firmware_class libcrc32c zlib_inflate evdev ext3 jbd mbcache dm_mirror dm_log dm_snapshot dm_mod cciss scsi_mod uhci_hcd ehci_hcd thermal processor fan thermal_sys [last unloaded: scsi_wait_scan] Oct 16 20:20:34 atlxvz30223 kernel: [215041.520115] Pid: 0, comm: swapper Tainted: G W 2.6.26-2-openvz-amd64 #1 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520118] Oct 16 20:20:34 atlxvz30223 kernel: [215041.520119] Call Trace: Oct 16 20:20:34 atlxvz30223 kernel: [215041.520122] <IRQ> [<ffffffff80234e10>] warn_on_slowpath+0x51/0x7a Oct 16 20:20:34 atlxvz30223 kernel: [215041.520143] [<ffffffff803cb4ec>] nf_iterate+0x41/0x7d Oct 16 20:20:34 atlxvz30223 kernel: [215041.520149] [<ffffffff803b0c72>] skb_gso_segment+0x88/0x1ae Oct 16 20:20:34 atlxvz30223 kernel: [215041.520155] [<ffffffff803b0f17>] dev_hard_start_xmit+0x17f/0x28d Oct 16 20:20:34 atlxvz30223 kernel: [215041.520162] [<ffffffff803b3b44>] dev_queue_xmit+0x1f0/0x2b4 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520169] [<ffffffff803d163d>] ip_rcv_finish+0x3a1/0x3c4 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520175] [<ffffffff803d1c30>] ip_rcv+0x26e/0x2c3 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520182] [<ffffffff803b08f5>] netif_receive_skb+0x3d8/0x455 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520194] [<ffffffffa00db063>] :bnx2x:bnx2x_rx_int+0xd13/0x1755 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520208] [<ffffffff803c5060>] tc_ctl_tfilter+0x12b/0x4d4 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520231] [<ffffffffa00e8063>] :bnx2x:bnx2x_poll+0xce/0x203 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520238] [<ffffffff8024abdd>] hrtimer_get_next_event+0x9b/0xab Oct 16 20:20:34 atlxvz30223 kernel: [215041.520244] [<ffffffff803b2e2a>] net_rx_action+0xab/0x1da Oct 16 20:20:34 atlxvz30223 kernel: [215041.520251] [<ffffffff80239fe5>] __do_softirq+0x96/0x15c Oct 16 20:20:34 atlxvz30223 kernel: [215041.520259] [<ffffffff8020d40c>] call_softirq+0x1c/0x28 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520264] [<ffffffff8020f58c>] do_softirq+0x3c/0x81 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520268] [<ffffffff80239f09>] irq_exit+0x81/0xc7 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520272] [<ffffffff8020f7ec>] do_IRQ+0xb9/0xd9 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520278] [<ffffffff8020c5ad>] ret_from_intr+0x0/0x19 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520281] <EOI> [<ffffffffa000c26d>] :processor:acpi_idle_enter_bm+0x2b3/0x327 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520300] [<ffffffff80271eed>] rcu_needs_cpu+0x32/0x41 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520307] [<ffffffff8039f514>] cpuidle_idle_call+0x7a/0xb2 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520312] [<ffffffff8039f49a>] cpuidle_idle_call+0x0/0xb2 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520316] [<ffffffff8020adb7>] cpu_idle+0x8e/0xb8 Oct 16 20:20:34 atlxvz30223 kernel: [215041.520328] Oct 16 20:20:34 atlxvz30223 kernel: [215041.520331] ---[ end trace e56ecebdb1614647 ]---
