But it happened several time recently, I am doing nothing, just letting it on.  it suddenly crashed and let me search for  "driver_irql_not_less_or_equal (mwlu97w8x64.sys)". what does this mean?

Hi allenyw80,

Thank you for the reply. I understand you are having the same issue on your replacement device and I know this is a frustrating situation for you. I'm here to guide you in the right direction. 

Please try the following:

  1. Back up your files.
  2. Do a reset.
  3. Go to Charms>Settings>PC settings>One Drive>Sync Settings>Turn off Sync your settings on this PC. This step will isolate the settings from other computers that might affect your Pro 2.
  4. Install all updates.
  5. Install your apps back one by one to see if the problem comes back with certain apps.
  6. If the problem continues, please contact our Support.

Best Regards,

Clare

    1. When and how is that happening?
    2. Any pending updates?
    3. What is the exact error message with the blue screen?
    4. Does shutting down the device and reboot solve the problem?

    Have you followed John1F suggestion above? Thanks for getting back to us.

    1. This happens once or twice a day on my work WiFi, but never happens on my home Wifi. It usually occurs right when I click on a link in Internet Explorer. It happens somewhat at random and is not predictable.
    2. No pending updates.
    3. Besides the standard blue screen information ":( Your PC ran into a problem etc..." it says "DRIVER_IRQL_NOT_LESS_OR_EQUAL (mwlu97w8x64.sys)".
    4. It randomly happens once or twice per day

    I've downloaded the driver pack as suggested by John1F. My Marvell drivers appear to be up to date.

    I have a Surface Pro 2. I am getting a bluescreen with this error almost daily. This is really impeding my ability to get work done on this machine which is the whole point of the Surface Pro line.

    Same thing here with original Surface Pro with all the updates.  I analyzed the memory dump file with the windows sdk debugging tool and it is clearly the marvell driver trying to access memory regions that it shouldn't be.  The crashes I have are during wifi-intensive activities (file transfers over network, etc...)

    Driver version 14.69.24052.168
