Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Gioele Barabucci, the next step is to fully reverse commit bisect in order to identify the fix commit. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?

I do not have the time to do a full git bisect, but I tried all the versions available from the mainline archive and I achieved some success.

The last kernel version that shows this error is v3.14.2-utopic (3.14.2-031402.201404262053). The first version without this problem is v3.14.3-utopic (3.14.3-031403.201405061153).

The fix has thus been added between v3.14.2 and v3.14.3.

Gioele Barabucci, thanks for updating this report with your current reverse commit bisect progress. When you have more time, and have identified the fix commit, please feel free to post the commit specifically and change this to Confirmed.

penalvch, no need to bisect: the bugzilla entry posted by Wulf Richartz contains the info about the commit that solves this problem for me (and creates an opposite problem for him).

Gioele Barabucci, which commit # specifically addresses your issue?

Dear Christopher M. Penalver, if a normal user like me can be asked to perform a git bisection on a kernel, I suppose it is reasonable to ask you to have a look at the linked bugzilla kernel report, read inside it the SHA of the commit that has landed into the stable branch and that solved this problem and finally track it up to the equivalent commit in the mainline kernel.

Gioele Barabucci, please do not be rude and passive aggressive. As there are multiple commits mentioned, and how you still have not advised which one specifically fixed your problem, please do not mark this from Incomplete until you mentioned explicitly the information requested in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1320282/comments/15 .

I had the same issue on a Lenovo Thinkcentre 93p Tiny running Ubuntu 14.04 x64, but the latest kernel update (3.13.0-32.57) seems to have fixed this.

Same issue with Lenovo M93z. Using Kernel 3.14.3, as suggested by Gioele Barabucci, solves the problem.
The Lenovo M93p Tiny had the same problem; however, on 2014-08-13 Lenovo released a BIOS update, which solves the issue.

So I recommend anyone still affected by this to just use the vanilla Kernel.

Simon Rettberg, thank you for your comment. So your hardware and problem may be tracked, could you please file a new report with Ubuntu by executing the following in a terminal while booted into the default Ubuntu kernel (not a mainline one) via:
ubuntu-bug linux

As mentioned in comment #19 this bug disappeared with kernel 3.13.0-32, but now it resurfaced with 3.13.0-44. It had no problems with the previous version 3.13.0-43 though.

Flashing the recent BIOS update (FBKTA5A released 2015-01-06) resolved the problem for me:
Shutdown works now with kernel 3.13.0-44.

As I did a bisect from 3.13.0-43 to 3.13.0-44 before I did the BIOS update here's the result anyway:

    xhci: Switch only Intel Lynx Point-LP ports to EHCI on shutdown.

    commit 0a939993bff117d3657108ca13b011fc0378aedb upstream.

    Patch "xhci: Switch Intel Lynx Point ports to EHCI on shutdown."
    commit c09ec25d3684cad74d851c0f028a495999591279 is not fully correct

    It switches both Lynx Point and Lynx Point-LP ports to EHCI on shutdown.
    On some Lynx Point machines it causes spurious interrupt,
    which wake the system: bugzilla.kernel.org/show_bug.cgi?id=76291

    On Lynx Point-LP on the contrary switching ports to EHCI seems to be
    necessary to fix these spurious interrupts.

Thank you madmat for the bisection.

Luckily the commit you have found is the same described in the linked kernel bugzilla entry.

If you guys want to do the update, the USB Drive UEFI BIOS Flash Package is your best bet. Make sure you use Windows (didn't work on Ubuntu and Wine for me) and a program called Rufus that allows you to create a MS-DOS bootable drive. BUT! Don't stick the files from USB Drive UEFI BIOS Flash Package on it when creating the bootable disk, DO IT AFTER.

You can create a bootable USB stick from Ubuntu using UNetbootin (from the repository) to install FreeDOS (see http://askubuntu.com/questions/46886/how-to-create-a-bootable-usb-stick-to-flash-a-bios). Booting with this and just executing the autoexec.bat to flash the BIOS worked for me.
