    Help needed in debugging bugcheck: 0xC000021a'


    My Windows 10 system continues to 'blue screen' with the bugcheck: 0xC000021a at startup and then will come up after a subsequent press of the restart button (I turned off 'automatic restart'). I installed Whocrashed to provide me with some information helpful information, but the information given is not very helpful in diagnosing what is causing this BSOD to occur. According to Whocrashed, an error occurred in a crucial user-mode subsystem - this is anything but helpful.
    The following information is included by Whocrashed: Bugcheck code: 0xC000021A (0xFFFFC000B0E975F0, 0xFFFFFFFFC0000001, 0x1, 0x80071D0000)
    Error: STATUS_SYSTEM_PROCESS_TERMINATED.

    I've had to restore my system a couple of times from a saved system image. The system runs without problem for a day or two and then start BSOD'ing with the above bugcheck.

    Any help would appreciated - I am on the verge of restoring my 8.1 system.

    I'm attaching the results from Windbg's analysis of a full memory dump. Hopefully there is some useful information in the three screenshots. Attachment 37167Attachment 37168Attachment 37169 I hope that these uploaded png files are readable. BTW, one of the first things that I did after installing Windows 10 was to disable automatic driver updates.

    I'm sorry, but I cannot read 2 images properly.
    Please use the tool from BSOD Posting Instructions and upload the zip file.

    You beat me to the punch - thanks hawkman.

    Axe0, hopefully you can read them once the text is magnified. I tried to minimize the amount of information that I thought would be relevant and incisive to someone familiar with Windows internals.

    Just those images is NOT enough.

    In fact, if the dumps only reveal that what you see in the images, then your windows would be corrupted. And that is just a thing that I don't beleave since there are other causes for this error.

    Do you have any devices recently installed? If so, remove these devices and see if it helps.

    Please do the following:

    • Open taskmanager
      • Go to the tab startup
      • disable everything

    • Search msconfig and open it
      • Go to the tab services
      • Check 'hide microsoft services'
      • Uncheck all other services
      • Click apply and click ok

    • Reboot if asked

    See if the problem persist, if the problem does not persist enable in the startup tab in taskmanager 1 item and in the services tab in msconfig also 1 service, reboot and see if the problem persist. Keep doing this until you find the culprit or there is nothing left.

    Please do the following:

    • Open an admin command prompt
    • Copy/paste "sfc/scannow" (without quotes) and press enter
    • When it finished reboot your system
    • Open again an admin command prompt
    • Enter sfc/scannow again


    If sfc/scannow does NOT say "Windows Resource Protection did not find any integrity violation", please upload the cbs.log file located at {windows partition}\Windows\Logs\CBS\, if the file is too large try a 3rd party uploader like dropbox, onedrive, google drive, mediafire etc.
    System File Check(SFC a.k.a. Windows Resource Protection) needs to have your system rebooted in order for sfc to try to fix the problems that it finds.

    I went through the 'clean boot' process and ran SFC with no negative results just before starting this thread. Just after my initial submittal, I installed some Microsoft fixes, and since then I've had no BSODs. I did not want to prematurely announce that my system was stable until I got a good three days of running without any BSOds. I also noticed that NTKRNLMP.EXE was updated as a result of one of the fixes. I'm keeping my fingers crossed and will review whatever is available regarding the fixes that seem to have relieved my problem.
