[Bug 1388072] Re: [Lenovo ThinkPad X230 Tablet] USB devices in docking station no longer working after resuming from long standby

 

Just tried Linux Kernel 3.18.0-031800rc2_3.18.0-031800rc2.201410262035
from the PPA which simply fails to properly boot and falls to a busybox
console because for some reason it fails to find the root drive.
Considering its an rc2 release it was not unexpected to run into some
unrelated issues. FYI the failed boot output was:

Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
  - Check rootdelay= (did the system waut long enough?)
  - Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-uuid/MYROOT-DRIVE-UUID does not exist. Dropping to a shell!

BusyBox v1.22.1 (Ubuntu 1:1.22.0-8ubuntu1) built-in shell (ash)

I'm now running 3.17.1-031701_3.17.1-031701.201410150735_all instead. If
I don't get the issue I will report back end of next week as it takes a
while for it to get triggered.

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

Status in “linux” package in Ubuntu:
  Incomplete

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.
