Responsible Changed From-To: freebsd-bugs->freebsd-net Over to maintainer(s). I'm seeing the exact same problem here as the original poster. Is anybody looking at this? Running FreeBSD 8.2-RELEASE-p1 amd64, from FreeNAS 8.0 sysctls: dev.em.0.%desc: Intel(R) PRO/1000 Network Connection 7.1.9 dev.em.0.%driver: em dev.em.0.%location: slot=0 function=0 dev.em.0.%pnpinfo: vendor=0x8086 device=0x108b subvendor=0x8086 subdevice=0x0000 class=0x020000 dev.em.0.%parent: pci1 dev.em.0.nvm: -1 dev.em.0.debug: -1 ... ifconfig: em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC> ether 00:15:17:31:c8:fe inet 139.171.199.13 netmask 0xffffff00 broadcast 139.171.199.255 media: Ethernet autoselect (1000baseT <full-duplex>) status: active dmesg | grep em0 em0: <Intel(R) PRO/1000 Network Connection 7.1.9> port 0xbc00-0xbc1f mem 0xff6e0000-0xff6fffff irq 16 at device 0.0 on pci1 em0: Using an MSI interrupt em0: [FILTER] em0: Ethernet address: 00:15:17:31:c8:fe -- Michael W. Lucas http://www.MichaelWLucas.com/, http://blather.MichaelWLucas.com/ Latest book: Network Flow Analysis http://www.networkflowanalysis.com/ mwlucas@BlackHelicopters.org, Twitter @mwlauthor This looks sounds like some features missing between if_em.c and if_lem.c Is this still happening in your tests? Timing out 2 year old ticket. If possible please take a look at 10.2r and see what your performance is. |
