In response to "Missing required logs": Single-user mode also has the
same problem.  When presented with the menu of what to do, I can't do
anything because of an unresponsive keyboard.

Due to the nature of the problem, I have no way of knowing or finding
out whether or not the system is frozen, or I just don't have input and
networking.

As for the upstream kernel, I can try it out tonight and report back.

Title:
  Fresh Ubuntu 64-bit install boots with no keyboard, mouse, or network

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Hardware: Cyberpower Z77 computer, including the following relevant
  parts:

  Motherboard: GIGABYTE GA-Z77-HD3 Intel Z77 Chipset 
  Video Card: nVidia 760
  Hard Drive: Samsung 128GB SSD, SATA3
  Keyboard: Moshi Luna USB
  Mouse: Razer USB gaming mouse

  "Try Ubuntu 14.04 without installing" from USB key: No problems.
  Install Ubuntu while in LiveCD environment: No problems (even browsed the web a bit).

  On reboot, Ubuntu boots to LightDM, and that's as far as I can go.
  The keyboard doesn't respond, though I can successfully toggle F-Lock
  on and off and the lights are on.  The mouse doesn't respond, and I
  see no cursor.  There's a notification in the upper-right hand corner
  that there are no connected networks.  I can't SSH in to get any logs.

  WORKAROUND: Boot from LiveUSB; mount and chroot into install; download
  and install Generic 3.14.1 MainLine kernel and reboot; everything is
  fine.  But I don't think I have to tell anyone how not-ideal that is,
  especially since chrooting these days involves three or four mount
  --bind commands that are difficult for people to remember.

  This has occurred on Ubuntu and Ubuntu Gnome spins.  This does not
  occur with Fedora 20 (the only other distro I've tried on this
  hardware).
