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.

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? ** Attachment added: "dmesg after resume" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1388072/+attachment/4251138/+files/dock-hang-on-resume-dmesg-linux.3.17.txt ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1388072 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.
