Hi list, I'm seeing a Unit Hang even with the latest e1000e driver 2.0.0 when doing scp test. this issue is easy do reproduced on SUN FIRE X2270 M2, just copy a big file (>500M) from another server will hit it at once.
Would you please help on this? device info: # lspci -s 05:00.0 05:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (Copper) (rev 06) # lspci -s 05:00.0 -n 05:00.0 0200: 8086:10bc (rev 06) # ethtool -i eth0 driver: e1000e version: 2.0.0-NAPI firmware-version: 5.10-2 bus-info: 0000:05:00.0 # ethtool -k eth0 Offload parameters for eth0: rx-checksumming: on tx-checksumming: on scatter-gather: on tcp segmentation offload: on udp fragmentation offload: off generic segmentation offload: on generic-receive-offload: on kernel log: ----------- e1000e 0000:05:00.0: eth0: Detected Hardware Unit Hang: TDH <6c> TDT <81> next_to_use <81> next_to_clean <6b> buffer_info[next_to_clean]: time_stamp <fffc7a23> next_to_watch <71> jiffies <fffc8c0c> next_to_watch.status <0> MAC Status <80387> PHY Status <792d> PHY 1000BASE-T Status <3c00> PHY Extended Status <3000> PCI Status <10> e1000e 0000:05:00.0: eth0: Detected Hardware Unit Hang: TDH <6c> TDT <81> next_to_use <81> next_to_clean <6b> buffer_info[next_to_clean]: time_stamp <fffc7a23> next_to_watch <71> jiffies <fffc9bac> next_to_watch.status <0> MAC Status <80387> PHY Status <792d> PHY 1000BASE-T Status <3c00> PHY Extended Status <3000> PCI Status <10> ------------[ cut here ]------------ WARNING: at net/sched/sch_generic.c:255 dev_watchdog+0x225/0x230() Hardware name: SUN FIRE X2270 M2 NETDEV WATCHDOG: eth0 (e1000e): transmit queue 0 timed out Modules linked in: autofs4 hidp rfcomm bluetooth rfkill lockd sunrpc cpufreq_ondemand acpi_cpufreq mperf be2iscsi iscsi_boot_sysfs ib_iser rdma_cm ib_cm iw_cm ib_sa ib_mad ib_core ib_addr iscsi_tcp bnx2i cnic uio ipv6 cxgb3i libcxgbi cxgb3 mdio libiscsi_tcp libiscsi scsi_transport_iscsi video sbs sbshc acpi_pad acpi_ipmi ipmi_msghandler parport_pc lp parport e1000e(U) snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device igb snd_pcm_oss serio_raw snd_mixer_oss snd_pcm tpm_infineon snd_timer snd soundcore snd_page_alloc i2c_i801 iTCO_wdt i2c_core pcspkr i7core_edac iTCO_vendor_support ioatdma ghes dca edac_core hed dm_snapshot dm_zero dm_mirror dm_region_hash dm_log dm_mod usb_storage sd_mod crc_t10dif sg ahci libahci ext3 jbd mbcache [last unloaded: microcode] Pid: 0, comm: swapper Not tainted 2.6.39-200.24.1.el5uek #1 Call Trace: [<c07d9ac5>] ? dev_watchdog+0x225/0x230 [<c045ba61>] warn_slowpath_common+0x81/0xa0 [<c07d9ac5>] ? dev_watchdog+0x225/0x230 [<c045bb23>] warn_slowpath_fmt+0x33/0x40 [<c07d9ac5>] dev_watchdog+0x225/0x230 [<c07d98a0>] ? dev_activate+0xb0/0xb0 [<c0468e82>] call_timer_fn+0x32/0xf0 [<c04bceb0>] ? rcu_check_callbacks+0x80/0x80 [<c046a76d>] run_timer_softirq+0xed/0x1b0 [<c07d98a0>] ? dev_activate+0xb0/0xb0 [<c0461a81>] __do_softirq+0x91/0x1a0 [<c04619f0>] ? local_bh_enable+0x80/0x80 <IRQ> [<c0462295>] ? irq_exit+0x95/0xa0 [<c087f8b8>] ? smp_apic_timer_interrupt+0x38/0x42 [<c08784f5>] ? apic_timer_interrupt+0x31/0x38 [<c046007b>] ? do_exit+0x11b/0x370 [<c065eae4>] ? intel_idle+0xa4/0x100 [<c078d9b9>] ? cpuidle_idle_call+0xb9/0x1e0 [<c0411d77>] ? cpu_idle+0x97/0xd0 [<c085cbbd>] ? rest_init+0x5d/0x70 [<c0b07a7a>] ? start_kernel+0x28a/0x340 [<c0b074b0>] ? obsolete_checksetup+0xb0/0xb0 [<c0b070a4>] ? i386_start_kernel+0x64/0xb0 ---[ end trace 5502b55cd4d4e5cb ]--- e1000e 0000:05:00.0: eth0: Reset adapter e1000e: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: Rx/Tx Thanks, Joe ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
