OK so things seems worse on 3.17.1. After resuming my laptop from about
10-11 hours sleep, not only were the inputs connected to the USB docks
not working, but after initial display my screen did not seem to be
updating (no flashing cursor on log in screen), and the keys and
trackpad on the laptop itself did not work. I disconnected the dock and
reconnected but still nothing. However, the screen on my external
monitor went off as expected but came back after reconnecting. I had
thought maybe a hard hang had happened but with the screen coming back
that seemed unlikely. I hit CTRL+ALT+F1 to switch to a terminal and
nothing happened. I then disconnected again and my laptop screen jumped
over to the terminal as if it had registered the CTRL+ALT+F1 previously.
Connecting again showed the terminal on my external screen but still the
USB keyboard connected to the dock did not work but disconnecting again
I found the laptop keys were working. I logged into the terminal and ran
dmesg. I then connected to the dock again and my USB keyboard and mouse
started working! :-/

After logging back into the desktop I found I had no wifi. I had seen this previously while testing a version of 3.17 in the past. After flicking my wifi hard switch off/on it still did not work and dmesg showed this odd bit (I know this is another issue but adding for prosperity):
 [44576.665593] iwlwifi 0000:03:00.0: RF_KILL bit toggled to disable radio.

[44584.452125] Bluetooth: hci0: BCM: patch brcm/BCM20702A0-0a5c-21e6.hcd not found

The wifi or ethernet still did not work and ifconfig showed the interfaces were missing so I ran:
$ sudo service networking restart
$ sudo service network-manager restart

and wifi came back alive (along with the bluetooth which I had not
actually checked).

So lots of fun with 3.17 :(

As for testing 3.18rc1, I am hesitant as I really don't like testing an
RC1 release on my production laptop. I might still but I'll likely wait
for an RC3 release to try next.

I'm attaching what my dmesg looked like after resume. If you are
interested I can attach another which was run after I got the networking
working again?

Title:
  [Lenovo ThinkPad X230 Tablet] USB devices in docking station no longer
  working after resuming from long standby

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  When my Lenovo Thinkpad x230t is attached to an Ultrabase Series 3
  dock and suspended for many hours, upon resume the USB ports on the
  dock, but not the laptop, stop working with peripherals (mouse,
  keyboard, usb drive).

  Shorter periods of standby seem unaffected unless the issues has
  already occurred. E.g. After a fresh boot if I suspend my laptop and
  resume after less than about 8 hours (I am not at all certain if the
  period of time is related. Just general observation), everything will
  continue to work fine. If however the issue has occurred at some point
  and I have disconnected and reconnected to work around the issue, and
  then I suspend for a short period of time (20 seconds) and resume, the
  dock's USB ports will no longer work unless I again disconnect the
  laptop from the dock and reconnect. So it seems once the issue has
  happened it will continue to happen until I reboot.
