Hi, My new servers always get Nic Down problem, and I think it's driver's problem. Can CoreOS Upgrade the firmware OR let me know how to upgrade by myself and fix it.
Only the new model servers have such message: dmesg: [26531.332930] i40e 0000:03:00.0 enp3s0f0: NIC Link is Down [26597.002838] i40e 0000:03:00.0 enp3s0f0: NIC Link is Up 1000 Mbps Full Duplex, Flow Control: None [26600.376443] i40e 0000:03:00.0 enp3s0f0: NIC Link is Down [26600.638532] i40e 0000:03:00.0 enp3s0f0: NIC Link is Up 10 Gbps Full Duplex, Flow Control: None [60150.554603] i40e 0000:03:00.0: TX driver issue detected, PF reset issued [60151.542604] i40e 00.0 device is FCoE capable [60151.571723] i40e 0000:03:00.0: i40e_ptp_init: added PHC on enp3s0f0 [60151.599953] i40e 0000:03:00.0: enabling bridge mode: VEPA [60151.706707] i40e 0000:03:00.0 enp3s0f0: NIC Link is Up 10 Gbps Full Duplex, Flow Control: None [60151.719669] i40e 0000:03:00.0 enp3s0f0: NIC Link is Down [60152.082937] i40e 0000:03:00.0 enp3s0f0: NIC Link is Up 10 Gbps Full Duplex, Flow Control: None [60152.299308] i40e 0000:03:00.0: TX driver issue detected, PF reset issued [60152.541311] i40e 00.0 device is FCoE capable [60152.570352] i40e 0000:03:00.0: i40e_ptp_init: added PHC on enp3s0f0 [60152.598533] i40e 0000:03:00.0: enabling bridge mode: VEPA [60152.704709] i40e 0000:03:00.0 enp3s0f0: NIC Link is Up 10 Gbps Full Duplex, Flow Control: None [62333.476868] i40e 0000:03:00.0: TX driver issue detected, PF reset issued [62333.918947] i40e 00.0 device is FCoE capable [62333.948119] i40e 0000:03:00.0: i40e_ptp_init: added PHC on enp3s0f0 [62333.976249] i40e 0000:03:00.0: enabling bridge mode: VEPA [62334.082936] i40e 0000:03:00.0 enp3s0f0: NIC Link is Up 10 Gbps Full Duplex, Flow Control: None [62334.095016] i40e 0000:03:00.0 enp3s0f0: NIC Link is Down [62334.465269] i40e 0000:03:00.0 enp3s0f0: NIC Link is Up 10 Gbps Full Duplex, Flow Control: None [62334.578785] i40e 0000:03:00.0: TX driver issue detected, PF reset issued [62334.916101] i40e 00.0 device is FCoE capable [62334.945156] i40e 0000:03:00.0: i40e_ptp_init: added PHC on enp3s0f0 [62334.973631] i40e 0000:03:00.0: enabling bridge mode: VEPA [62335.080514] i40e 0000:03:00.0 enp3s0f0: NIC Link is Up 10 Gbps Full Duplex, Flow Control: None lspci |grep 10GbE 03:00.0 Ethernet controller: Intel Corporation Ethernet Controller X710 for 10GbE backplane (rev 01) 03:00.1 Ethernet controller: Intel Corporation Ethernet Controller X710 for 10GbE backplane (rev 01) cat /etc/os-release NAME=CoreOS ID=coreos VERSION=899.17.0 VERSION_ID=899.17.0 BUILD_ID=2016-05-03-2151 PRETTY_NAME="CoreOS 899.17.0" ANSI_COLOR="1;32" HOME_URL="https://coreos.com/"; BUG_REPORT_URL="https://github.com/coreos/bugs/issues"; Not only the latest stable version.
