Message-ID: <20131114101806.GJ5513@ntm.wq.cz> Date: Thu, 14 Nov 2013 11:18:07 +0100 From: Milan Kocian <milon@...cz> To: netdev@...r.kernel.org Cc: jeffrey.t.kirsher@...el.com, jesse.brandeburg@...el.com Subject: NETDEV WATCHDOG: eth0 (e1000e): transmit queue 0 timed out hi, its probably for intel's guys ... I see 'Detected Hardware Unit Hang' in log repeatedly until transmit hangs forever (until reboot:-)). I tried old fixeep script which I got from Jesse Brandeburg some years ago but no success. Any ideas ? Many thanks for any answer. kernel 3.10.18 Outputs & logs: ethtool -i eth0 driver: e1000e version: 2.3.2-k firmware-version: 0.13-4 bus-info: 0000:00:19.0 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes supports-priv-flags: no 00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 04) Subsystem: Intel Corporation Device 2036 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Interrupt: pin A routed to IRQ 42 Region 0: Memory at f7d00000 (32-bit, non-prefetchable) [size=128K] Region 1: Memory at f7d35000 (32-bit, non-prefetchable) [size=4K] Region 2: I/O ports at f080 [size=32] Capabilities: [c8] Power Management version 2 Flags: PMEClk- DSI+ D1- D2- AuxCurrent=0mA PME(D0+,D1-,D2-,D3hot+,D3cold+) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=1 PME- Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+ Address: 00000000fee0100c Data: 4172 Capabilities: [e0] PCI Advanced Features AFCap: TP+ FLR+ AFCtrl: FLR- AFStatus: TP- Kernel driver in use: e1000e e1000e 0000:00:19.0 eth0: Detected Hardware Unit Hang: TDH <a9> TDT <7> next_to_use <7> next_to_clean <a6> buffer_info[next_to_clean]: time_stamp <4af1c> next_to_watch <a9> jiffies <4b12e> next_to_watch.status <0> MAC Status <80083> PHY Status <796d> PHY 1000BASE-T Status <3c00> PHY Extended Status <3000> PCI Status <10> e1000e 0000:00:19.0 eth0: Detected Hardware Unit Hang: TDH <a9> TDT <7> next_to_use <7> next_to_clean <a6> buffer_info[next_to_clean]: time_stamp <4af1c> next_to_watch <a9> jiffies <4b386> next_to_watch.status <0> MAC Status <80083> PHY Status <796d> PHY 1000BASE-T Status <3c00> PHY Extended Status <3000> PCI Status <10> e1000e 0000:00:19.0 eth0: Detected Hardware Unit Hang: TDH <a9> TDT <7> next_to_use <7> next_to_clean <a6> buffer_info[next_to_clean]: time_stamp <4af1c> next_to_watch <a9> jiffies <4b5de> next_to_watch.status <0> MAC Status <80083> PHY Status <796d> PHY 1000BASE-T Status <3c00> PHY Extended Status <3000> PCI Status <10> e1000e 0000:00:19.0 eth0: Detected Hardware Unit Hang: TDH <a9> TDT <7> next_to_use <7> next_to_clean <a6> buffer_info[next_to_clean]: time_stamp <4af1c> next_to_watch <a9> jiffies <4b836> next_to_watch.status <0> MAC Status <80083> PHY Status <796d> PHY 1000BASE-T Status <3c00> PHY Extended Status <3000> PCI Status <10> ------------[ cut here ]------------ WARNING: at net/sched/sch_generic.c:255 dev_watchdog+0x1cc/0x1e0() NETDEV WATCHDOG: eth0 (e1000e): transmit queue 0 timed out Modules linked in: tun ipv6 xt_nat xt_conntrack xt_tcpudp xt_LOG xt_limit iptable_nat nf_nat_ipv4 nf_nat iptable_filter ip_tables x_tables nf_conntrack_ipv4 nf_defrag_ipv4 nf_conntrack ehci_pci ehci_hcd e1000e coretemp xhci_hcd hwmon usbcore crc32_pclmul iTCO_wdt iTCO_vendor_support lpc_ich crc32c_intel mfd_core ptp pps_core usb_common i2c_i801 i2c_core microcode CPU: 0 PID: 0 Comm: swapper/0 Not tainted 3.10.18-core2-router18 #3 Hardware name: /DQ77KB, BIOS KBQ7710H.86A.0049.2013.0130.1732 01/30/2013 c12ad3ea c102836e c135ece0 f540bf58 000000ff c123b38c c123b38c 00000000 f4d98000 000005dc 0004b964 c10283c3 00000009 f540bf40 c135ece0 f540bf58 c123b38c c135bdec 000000ff c135ece0 f4d98000 f8184740 00000000 00000100 Call Trace: [<c12ad3ea>] ?
