[Bug 1529266] Re: [HP Spectre x360 - 13-4005dx] suspend/resume failure


The reverse bisect from 4.3 to 4.4-rc1 shows the bug was "fixed" in
d55fc37, "Pull i2c updates from Wolfram Sang".  That seems unrelated to
the bad commit identified in 4.2.6 (0691783, "NFSv4.1: Fix a protocol
issue with CLOSE stateids"), so either I botched the bisect or there
might be something more complex going on.

For the record, here's the bisect log:

  [HP Spectre x360 - 13-4005dx] suspend/resume failure

Status in linux package in Ubuntu:

Bug description:
  Upgrading from 15.04 to 15.10 my Spectre x360 is no longer able to
  suspend (either shutting the lid or sudo pm-suspend in a terminal).
  This is (AFAIK) the same problem as #1502531.

  Following the instructions in #1502531 I updated to mainline kernel
  v4.4-rc6-wily and had no problems suspending the machine.

  At the request of Chris Penalver I did the following:
   1. rebooted to the Ubuntu 4.2.0-22-generic kernel (since I've been running 4.4)
   2. ran sudo pm-suspend, system locked up (frozen mouse, caps lock key didn't light up when pressed)
   3. held the power button to shut laptop off
   4. booted into the 4.2.0-22-generic kernel again
   5. ran ubuntu-bug linux to generate this bug report
