Title:
  Unable to hibernate HP6530b with fresh install of Ubuntu 14.04

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I am able to put my computer to suspend mode (STR) but not to
  hibernation mode (STD). I have already allocated enough of swap space
  on a separate disk partition. But it is not working.

  I have not been able to isolate the problem between suspend and
  resume, and so was testing hibernation support as suggested at
  https://wiki.ubuntu.com/DebuggingKernelHibernate and
  https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt.
  Specifically, I was testing using commands like the following:

  |  cd /sys/power
  |  echo shutdown > disk
  |  echo platform > pm_test
  |  echo disk > state

  So far all the suspend tasks work okay; still no joy!!

  
  == My observations ==

  I came across two interesting things in the dmesg output:

  1. PCI HotPlug is always reporting existing devices while trying to
  resume.

  |  [ 3098.516294] pciehp 0000:00:1c.5:pcie04: Device 0000:85:00.0 already exists at 0000:85:00, cannot hot-add
  |  [ 3098.516300] pciehp 0000:00:1c.1:pcie04: Device 0000:02:00.0 already exists at 0000:02:00, cannot hot-add
  |  [ 3098.516304] pciehp 0000:00:1c.5:pcie04: Cannot add device at 0000:85:00
  |  [ 3098.516307] pciehp 0000:00:1c.1:pcie04: Cannot add device at 0000:02:00

  I suspect these devices (which happen to be for the ethernet and the
  wifi) are not allowing the suspend to proceed. A little bit of
  searching also led me to
  http://comments.gmane.org/gmane.linux.kernel.pci/19876 which indicates
  that this problem may be a regression.

  2. ACPI is also complaining about AE_AML_PACKAGE_LIMIT exception,
  although only once, at the boot time.

  |  [   16.019199] i915 0000:00:02.0: fb0: inteldrmfb frame buffer device
  |  [   16.019201] i915 0000:00:02.0: registered panic notifier

  |  [   16.344378] ACPI Exception: AE_AML_PACKAGE_LIMIT, Index (0x000000005) is beyond end of object (length 0x5) (20131115/exoparg2-420)
  |  [   16.344388] ACPI Error: Method parse/execution failed [\_SB_.PCI0.GFX0._DOD] (Node ffff8800b9a622f8), AE_AML_PACKAGE_LIMIT (20131115/psparse-536)
  |  [   16.344399] ACPI Exception: AE_AML_PACKAGE_LIMIT, Evaluating _DOD (20131115/video-1246)
  |  [   16.500280] ACPI: Video Device [GFX0] (multi-head: yes  rom: no  post: no)
  |  [   16.502361] acpi device:04: registered as cooling_device7

  This need not be of any consequence; just something I thought would be
  interesting.

  == Addtional information ==

  1. Earlier, I had blacklisted all tpm* modules after I had discovered
  that the tpm_tsi module was trying to access the TPM chip. The problem
  has existed before as well as after this blacklisting. FYI, the
  blacklist information is pasted below:

  |   # remove all tpm (trusted platform module) drivers
  |   # location: /lib/modules/$(uname -r)/kernel/drivers/char/tpm/*
  |   blacklist tpm_atmel
  |   blacklist tpm_i2c_atmel
  |   blacklist tpm_i2c_infineon
  |   blacklist tpm_i2c_nuvoton
  |   blacklist tpm_i2c_stm_st33
  |   blacklist tpm_infineon
  |   blacklist tpm_nsc
  |   blacklist xen-tpmfront

  2. Here is the output of the relevant commands directly from my
  terminal:
