Q: kernel_task 100% usage after panic attack

Hello! Sorry for bothering but I'm having this issue that i just can't solve. The thing is, on my activity monitor the process " Kernel task" is always between 100-120 % of cpu! It started  2 days ago after my computer got a panic attack. These are solutions i tried:

  • Logged in safe mode - the issue is present.
  • SMC and PRAM reset.
  • Removing the kext where is my laptop model in IOPlatformpluginfamily (nothing happened and i reverse it).
  • Cleaned all caches manually from /library/caches, system/library/caches and ~/library/caches.
  • AHT and there no problems.

 

The only thing that misses is the reinstall of the osx, which i haven't done because i did a fresh install one month ago. Is it the logic board? i hope not..

I leave a etrecheck report just in case you spot something unusual although  i haven't installed much software.

 

PS: I installed istats after i detected this issue so i could monitor the temperature and control the fans, just in case. And those invalid signatures in the report appear              after i cleaned the caches.

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.

Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.

If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

Keep your confidential data secure during hardware repair.

Apple recommends that you deauthorize a device in the iTunes Store before having it serviced.

*An SSD doesn't need to be zeroed.

    When you have kernel panics, the pertinent information is in the panic reports, not in the output of some random app that you downloaded.

    These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.

    Please launch the Console application in any one of the following ways:

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad and start typing the name.

    In the Console window, select

              DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports

    (not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select

              View ▹ Show Log List

    from the menu bar.

    There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.

    If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.

    In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)

    Please don’t post other kinds of diagnostic report.

    I know the report is long, maybe several hundred lines. Please post all of it anyway.

    When you post the report, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

    If you have an account on Pastebin, please don't select Private from the Paste Exposure menu on the page, because then no one but you will be able to see it.

    Has there been just one panic, or more than one?

    Yes, there's been more. But since this last one, where the kernel_task got to such high cpu levels, they never occurred again.

    The kernel is using excessive processor cycles. Below are some possible causes for the condition. Some may not apply to you.

    FileVault

    Please open the Security & Privacy pane in System Preferences and select the FileVault tab. If there's an indication that encryption or decryption is in progress, wait (maybe several hours) for it to finish and see whether there's an improvement.

    Throttling

    When it gets high temperature readings from the hardware, or low voltage readings from the battery of a MacBook, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:

    ☞ a buildup of dust on the logic board

    ☞ high ambient temperature

    ☞ a worn-out or faulty battery in a portable

    ☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component

    Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.

    If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on AC power, charging is causing the machine to heat up. That behavior may be normal for some models, but it may also be an indication of a hardware fault.

    Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

    If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.

    Installed software

    User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.

    If you're not sure what software could be contributing to the problem, please hold down the option key and select

              System Information...

    from the Apple menu. The System Information window will open. Select

              Software ▹ Extensions

    from the menu on the left. After a delay of a minute or so, a list of all installed kernel extensions should appear in the upper right pane of the window.

    In the extension list, click the heading of the column Obtained from twice to sort it by source, with Apple at the bottom. At or near the top, you may see some third-party extensions. Select one, and information about it, including Location, will appear in the lower right pane of the window. What do you see?

    Corrupt NVRAM or SMC data

    Sometimes the problem is cleared up by resetting the NVRAM or the SMC.

    External display

    Connecting an external display to some MacBook Pro models while the lid is open may cause this issue. If applicable, use the external display in clamshell mode.

    Other peripherals

    Disconnect all wired peripherals except those needed to start up, and remove all third-party expansion cards (if applicable to your model.) If the problem is resolved, reconnect the devices one at a time until you identify the culprit.

    The only 3rd party extension i see are these:

    1. Accusy6xxxx
    2. ATTOCelerityFC
    3. ATTOExpressPCI4
    4. ATTOExpressSASHBA
    5. ATTOExpressSASHBA3
    6. ATTOExpressSASRAID
    7. JMicronATA
    8. ArcMSR
    9. ATTOCelerityFC8
    10. ATTOExpressSASHB2
    11. ATTOExpressSASRAID2
    12. CalDigitHDProDrv
    13. HighpointIOP
    14. HighPointRR
    15. PromiseSTEX
    16. SoftRAID

     

    None of them were loaded, and only the first 7 are unrecognized. Can i just delete this and see if solves my problem?

    No, none of those is causing the problem. What about the other steps?

    Here they are:

    • FileVault  

              It's disable.

    • AHT

              No problems, although i haven' t done the extension test.

    • Throttling

              No dust, ambient temperature okay,

              The battery is at it's middle capacitance (the OSX says it needs to be changed) .

              The fan seems okay, i can control it fairly well with stats.

    • Secure mode

              I  didn't this step because i installed istats after this issue came up.

    • PRAM and SMC

              I have already done this although i'm not sure if i succeeded at reseting PRAM, i didn't notice any differences and the starting chime no longer appears.

    • External Display and periphericals

              Never had any of these.


    Just one thing, observing kernel's log at console. I spotted a lot of errors like "SMC::smcInitHelper ERROR", "SMC::smcReadKeyAction ERROR", "SystemUIServer[*] caught causing excessive wake ups"  And a lot of sound assertions "Sound assertion in AppleHDAEngine". It's like they are in a loop, repeat after x minutes.

    Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.

    Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.

    If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

    Keep your confidential data secure during hardware repair.

    Apple recommends that you deauthorize a device in the iTunes Store before having it serviced.

    *An SSD doesn't need to be zeroed.

    Ok thanks for your help.

    Just two more questions. If i reinstall the OSX (in this case mavericks) using recover partition, will i need a mavericks installer?

    And in the case i take my machine to genius appointment or an authorized service provider and they say something like my logic board is damaged and needs replacement. Is it worth in a model this old?  

     

    Again, thanks for your attention and time!

    will i need a mavericks installer?

    The installer package is downloaded automatically.

    Is it worth in a model this old?

    I have to confess that I didn't notice in the panic report that you have a 2010 model. That makes it too old to be serviced by Apple, unless you happen to live in California (don't ask me why.) An independent service provider might be willing, but the parts may no longer be available. As for whether it's worth it, that's for you to decide when you get a repair estimate. I wouldn't bother, myself.
