Hanno, could you please test the latest upstream kernel available from
the very top line at the top of the page (the release names are
irrelevant for testing, and please do not test the daily folder)
following https://wiki.ubuntu.com/Kernel/MainlineBuilds ? It will allow
additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, Y, and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this
bug's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Title:
  load >= 1 while idle for no obvious reason with ACPI

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  My idling server will stay at load >=1 if ACPI is active, for no
  obvious reason.

  Adding "acpi=off" to grub will resolve this and load falls to 0.0x as
  expected.

  But I use the power button to tell the box to shut down and without
  ACPI, systemd cannot respond to the power button's ACPI event.

  My server is an Acer Easystore H340, that's a small NAS box with four
  disk bays and an Atom 230 in it. That's standard x86 hardware capable
  of running x86_64 kernels.

  Recently, it was upgraded from 14.10 to 15.04 x86_64. Only after that
  upgrade did I notice the load >= 1 problem, although it may have been
  there in previous releases, already.

  No idea how to debug this.

  To resolve this, I either need
  - a way to fix load >= 1 with ACPI
  or
  - a way to respond to the power button without ACPI

  Thanks.
