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

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?

Elrepo.org has updated drivers for both e1000e and r8169 devices (I'm guessing it's probably the kmod-r8168 you'd need). You could try these to see if they resolve the issue.

If you want more help identifying the correct driver for your hardware, see FAQ #4 here:

The network card for eth1 seems to have disappeared somehow. On the problem host:

# /sbin/lspci -nn | grep -i net 00:19.0 Ethernet controller [0200]: Intel Corporation 82567V-2 Gigabit Network Connection [8086:10ce] #

On another but nearly identically configured host (same MB and additional NIC:

# /sbin/lspci -nn | grep -i net00:19.0 Ethernet controller [0200]: Intel Corporation 82567V-2 Gigabit Network Connection [8086:10ce] 01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev 03) 04:04.0 Serial controller [0700]: NetMos Technology PCI 9835 Multi-I/O Controller [9710:9835] (rev 01)

Where did eth1 on the first host go? How do I get it back? A restart?

Faulty hardware maybe? Try a reboot and see if it reappears. If it's located on a card try reseating the card (although I suspect this is an integrated NIC on the motherboard?).

The chipset is not necessarily the same in the second example (different revision); RTL8111/8168B is not RTL8168d/8111d. They probably do use the same driver but I'd need to see the Vendor:Device ID pairing to know for sure.
