(Get the code!)
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.
[44576.920342] usb 1-1.4: USB disconnect, device number 3
[44584.021782] iwlwifi 0000:03:00.0: RF_KILL bit toggled to enable radio.

[44584.451323] bluetooth hci0: Falling back to user helper
[44584.452125] Bluetooth: hci0: BCM: patch brcm/BCM20702A0
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?
