kworker uses 70-90% of a CPU core (hyperthreaded)

Bug Description

I see high (70-90%) cpu usage from a kworker thread. Usually kworker/0:1 or kworker/0:2. This does not always happen. On some boots all is fine but once it shows, rebooting does not make it go away.

WORKAROUND: Execute:
echo "disable" > /sys/firmware/acpi/interrupts/gpe13

why is this incomplete? should I add something?

Sorry to budge in. Experiencing the exact same problem on my brand new Samsung Chronos Series 7 using Arch Linux.

Just thought you might be interested in a dirty workaround that takes CPU usage down (at the expense of some problem? dunno, still haven't experienced any):

1 - Locate problematic GPE in /sys/firmware/acpi/interrupts/ (just cat each gpe until you see one with a high interrupt count - mine was gpe13)
2 - execute: echo disable > /sys/firmware/acpi/interrupts/gpexx (substitute for the one you found on the previous step).

If that works, you might want to execute it on every system launch (using systemd or whatever ubuntu uses for that) and after resume (I'm using pm-utils for that).

I suspect either some driver not playing well or samsung BIOS problem (although I still get it after update) are creating a never-ending interrupt stream. I saw no difference between lsmod when boot worked ok or when the high CPU usage was detected so maybe it is execution-order related?

I'm also getting [drm:__gen6_gt_force_wake_mt_get] *ERROR* Timed out waiting for forcewake old ack to clear. on boot. This might be related?

@Alexandre: great work man! thank you very much, your solution is really appreciated.

I'm experiencing the same problem as exposed here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/887793
(this bug it's a duplicate of the 887793, but because of the solution is really appreciated)

I've tried your solution (mine too is the gpe13, so I think there is some magic in this number lol) and the CPU is quickly returned to a normal state.

Though the workaround works, this is a serious issue (definitely above "Medium" importance and needs to be solved at the kernel level. WTH is interrupt 13 anyway? Maybe it is invoking/reporting something important.

I could not execute the echo command from a normal terminal, however it works on boot - added to /etc/rc.local file (Ubuntu's "user" startup script). The suspend fix is described in the original (887793) bug thread: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/887793/comments/114

Thank you very much!!

Mio, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

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

Mio, please don't change the Description. It is filled with old, irrelevant, and speculative statements that confuse and hinder developers resolving the problem.

I did some more research and found this kernel bug https://bugzilla.kernel.org/show_bug.cgi?id=53071 which seems to descibe exactly this issue. In that thread there is mentioned that a bios update might fix the problem.
Thus I went hunting for an update for my model since the Software Update tool from Samsung does not show any updates. Eventually i found this https://www.samsung.com/us/support/owners/product/np700z7c (could not find an equivalent on the german site..). At "firmware" there is a download button that does work for me but in the HTML code there is a link http://org.downloadcenter.samsung.com/downloadfile/ContentsFile.aspx?CDSite=US&CttFileID=4986477&CDCttType=FM&ModelType=C&ModelName=NP700Z7C-S01US&VPath=FM/201203/20120305100525911/BIOSUpdate.exe
which leads to a BIOS Update Tool (changing the modelname to my model leads to the same download)
lunching this from windows allowed me to update to version P06AAE from P04AAE.

I can confirm that this does NOT solve the issue of the gpe13 interrupt spamming.

In that kernel bug it is mentioned that the output of dmidecode might be / is useful to fix this. Thus I have attached that here too (executed after the bios update as you can see)

Ok I just saw it's a GPE issue. Can you try latest mainline kernel [1]? There are several GPE/EC fixes.

I can confirm that the issue is present with 4.17-rc6 too

Does this laptop have a free fall sensor?

Seems like gpe13 tries to notify your SATA controller something. Or maybe it's related to the ExpressCache?

    Scope (_GPE)
    {
        Method (_L13, 0, NotSerialized) // _Lxx: Level-Triggered GPE
        {
            If ((PFLV == FDTP))
            {
                Return (Zero)
            }

            GPE3 = Zero
            GL08 |= 0x10
            Notify (\_SB.PCI0.SAT0, 0x82) // Device-Specific Change
            Return (Zero)
        }
    }

I dont't believe my laptop has a free fall sensor, didn't ever hear of such a thing. How do I check?
It does have ExpressCache though.
My vague hypothesis is that it has something to do with the ODD but i don't understand enough of this for being able to verify any of this without instructions.
