I wanted to comfirm that I had the touchpad/keyboard not working after
suspend, running Ubuntu Saucy GNOME 13.10 Beta 1 updated on a Toshiba
P50-ABT2G22 Haswell-based laptop. The trick of:

"Adding Grub parameter atkbd.reset worked for many. Set
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash atkbd.reset" in
/etc/default/grub, run 'sudo update-grub' and reboot."

worked for me, and I can confirm both keyboard & touchpad work after a
suspend with this kernel parameter added.

Title:
  Synaptics touchpad ceases functioning after suspend and resume.

Status in Ubuntu:
  Invalid
Status in “cruft” package in Ubuntu:
  Invalid
Status in “linux” package in Ubuntu:
  Won't Fix
Status in “linux-source-2.6.20” package in Ubuntu:
  Won't Fix

Bug description:
  After suspending the notebook, resume works fine except that the
  Synaptics touchpad no longer responds to any input.

  Restarting the X server does not help.

  Attempting to cat /dev/input/mice at the console and then moving the
  touchpad does not show any input being received. The touchpad which
  had been /dev/input/mouse0 is no longer listed after the resume.

  This bug was present in Dapper and still exists in the current
  (2006-09-11) build of Edgy as well and Karmic Koala (9.10)

  Gateway MX6625 Notebook
  Centrino Chipset
  Synaptics Touchpad

  Also affects
  Gateway MX6025 Notebook with Karmic Koala 9.10
  HP EliteBook 2530p with Ubuntu Lucid 10.04 LTS amd64
  Fujitsu Siemens Computer Aminlo Si1520 with Ubuntu Lucid 10.04 LTS
  and others.

  Multiple ways to bypass the bug are suggested in comments. Adding Grub
  parameter atkbd.reset worked for many. Set
  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash atkbd.reset" in
  /etc/default/grub, run 'sudo update-grub' and reboot.
