I'm still new to this Kubuntu bug fixing process and the preceding comment doesn't say whether this is directed at the reporter (me), but I went ahead and installed the 3.13.0-45 kernel packages from trusty-proposed yesterday. Tested on home and office LAN: booted with just Wifi, docked the laptop, and it acquired the wired connection without a hitch. Encountered no other issues either.

The following upstream patch resolved this problem for us in Kubuntu 14.04 LTS kernels 3.13.0-34-generic and 3.13.0-40-generic: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/drivers/net/ethernet/intel/e1000e?id=b20a774495671f037e7160ea2ce8789af6b61533 Please incorporate this patch in the Kubuntu kernel so that the /lib/modules/3.13.0-XX- generic/kernel/drivers/net/ethernet/intel/e1000e/e1000e.ko module doesn't have to rebuilt manually every time we follow a kernel update. Thanks.
