  • Hi,

    All of the attached DMP files are of the BAD_POOL_CALLER (c2) bug check.

    This indicates that the current thread is making a bad pool request.

    BugCheck C2, {7, 11c1, 81c4eac0, 81c4eac8}

    The 1st parameter of the bug check is 7 which implies that there was an attempt to free a pool twice/pool which was already freed.

    1: kd> !pool 81c4eac8
    GetPointerFromAddress: unable to read from 81c88470
    Unable to read MiSystemVaType memory at 81c5e000
    

    Can't seem to run !pool, let's refer to the call stack instead:

    1: kd> k
    ChildEBP RetAddr  
    8bf89a4c 81c3bcf2 nt!KeBugCheckEx
    8bf89ae4 82c5abf9 nt!ExDeferredFreePool+0xe7a

    It appears the driver that attempted to free pool that was already freed was ewusbnet.sys. This is a USB NDIS Miniport Driver - likely for Huawei Mobil Connect package.

    1: kd> lmvm ewusbnet
    start    end        module name
    8f74e000 8f783000   ewusbnet T (no symbols)           
        Loaded symbol image file: ewusbnet.sys
        Image path: \SystemRoot\system32\DRIVERS\ewusbnet.sys
        Image name: ewusbnet.sys
        Timestamp:        Wed Oct 21 07:46:07 2009

    The drivers are pretty dated for Windows 8.1 (2009). I'd check for an update ASAP -
    http://consumer.huawei.com/en/support/downloads/index.htm or try the carrier that provided the modem

    If no updates available, you'll need to remove the device itself and connect either wirelessly with a different adapter or via ethernet.

    Regards,
