This one? [ 10.344571] r8169 0000:02:00.0: eth0: RTL8168d/8111d at 0xf8064000, bc:ae:c5:27:19:6f, XID 083000c0 IRQ 41 > Did you enable some offload feature (see 'ethtool -k') ?

Here's the ethtool -k output: Offload parameters for p10p1: rx-checksumming: on tx-checksumming: off scatter-gather: off tcp-segmentation-offload: off udp-fragmentation-offload: off generic-segmentation-offload: off generic-receive-offload: on large-receive-offload: off rx-vlan-offload: on tx-vlan-offload: on ntuple-filters: off receive-hashing: off Thanks, -- Nick Bowler, Elliptic Technologies (http://www.elliptictech.com/)
