I am trying to transport a dd image between to hosts over a cross linked gigabit connection. Both hosts have an eth1 configured to a non routable ip addr on a shared network. No other devices exist on this link. When transferring via sftp I received a stall warning. Checking the logs I see this: dmesg | grep eth e1000e 0000:00:19.0: eth0: (PCI Express:2.5GT/s:Width x1) 00:1c:c0:f2:1f:bb e1000e 0000:00:19.0: eth0: Intel(R) PRO/1000 Network Connection e1000e 0000:00:19.0: eth0: MAC: 7, PHY: 8, PBA No: FFFFFF-0FF r8169 0000:01:00.0: eth1: RTL8168d/8111d at 0xffffc9000187c000, 00:0a:cd:1d:44:fe, XID 081000c0 IRQ 31 r8169 0000:01:00.0: eth1: jumbo features [frames: 9200 bytes, tx checksumming: ko] ADDRCONF(NETDEV_UP): eth0: link is not ready device eth0 entered promiscuous mode r8169 0000:01:00.0: eth1: invalid firwmare r8169 0000:01:00.0: eth1: unable to load firmware patch rtl_nic/rtl8168d-1.fw (-22) r8169 0000:01:00.0: eth1: link down r8169 0000:01:00.0: eth1: link down ADDRCONF(NETDEV_UP): eth1: link is not ready r8169 0000:01:00.0: eth1: link up ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready e1000e: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: None ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready br0: port 1(eth0) entering learning state eth1: no IPv6 routers present eth0: no IPv6 routers present br0: port 1(eth0) entering forwarding state r8169 0000:01:00.0: eth1: link down r8169 0000:01:00.0: eth1: link up r8169 0000:01:00.0: eth1: link down r8169 0000:01:00.0: eth1: link up This may, or may not, be related to this bug: https://bugzilla.kernel.org/show_bug.cgi?id=12411 Is there some way to confirm whether or not this is the case. Is there a work-around for it if it is this bug? If it is not then has anyone any idea what is happening and how to fix it? -- *** E-Mail is NOT a SECURE channel *** James B.
