I don't think that is going to be practical. If I get some spare time I
will try a live 12.04 environment but this bug normally takes days to
occur and I will just not be able to run the live environment for that
long. I may be able to test the kernel from 14.04 if you have
suggestions on how to do that or should I just grab the same version
from the kernel PPA? However I am concerned with hardware support as I
recall Intel Ivybridge based chips not being so great on 12.04. I
started using Ubuntu with this laptop from 12.10.

Thanks.

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.
