Hello all, this happened right now on my server using 3.13.0-39-generic . The NIC was under I/O due to concurring backups.
In my syslog i found many lines of: Nov 10 23:21:17 server kernel: [759261.907344] e1000e 0000:00:19.0 eth1: Detected Hardware Unit Hang: Nov 10 23:21:17 server kernel: [759261.907344] TDH <de> Nov 10 23:21:17 server kernel: [759261.907344] TDT <ed> Nov 10 23:21:17 server kernel: [759261.907344] next_to_use <ed> Nov 10 23:21:17 server kernel: [759261.907344] next_to_clean <dc> Nov 10 23:21:17 server kernel: [759261.907344] buffer_info[next_to_clean]: Nov 10 23:21:17 server kernel: [759261.907344] time_stamp <10b4f2f76> Nov 10 23:21:17 server kernel: [759261.907344] next_to_watch <de> Nov 10 23:21:17 server kernel: [759261.907344] jiffies <10b4f30c5> Nov 10 23:21:17 server kernel: [759261.907344] next_to_watch.status <0> Nov 10 23:21:17 server kernel: [759261.907344] MAC Status <40080183> Nov 10 23:21:17 server kernel: [759261.907344] PHY Status <796d> Nov 10 23:21:17 server kernel: [759261.907344] PHY 1000BASE-T Status <3800> Nov 10 23:21:17 server kernel: [759261.907344] PHY Extended Status <3000> Nov 10 23:21:17 server kernel: [759261.907344] PCI Status <10> # lspci 00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v2/Ivy Bridge DRAM Controller (rev 09) 00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 05) 00:1a.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.4 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 5 (rev b5) 00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev a5) 00:1f.0 ISA bridge: Intel Corporation C204 Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 01:00.0 RAID bus controller: Adaptec Series 6 - 6G SAS/PCIe 2 (rev 01) 02:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection 03:03.0 VGA compatible controller: Matrox Electronics Systems Ltd.
