NDIS Miniport Crash in NDIS!ndisMSendComplete

    My miniport driver is crashing when it calls NdisMSendComplete. I'm
    validating the AdapterHandle and Packet parameters, so I know I'm not calling
    it with bad pointers. After the crash, I look at the packet in the WinDbg,
    and the only thing that I see that looks suspicious is that
    Packet->Private->Head is apparently incorrect. It's pointing to a
    MappedSystemVa of 0x4, and StartVa of 0x2. Tail however looks like it has a
    good list. My code never touches anything in the Packet->Private since it is
    supposed to be opaque to the miniport. How do I go about debugging an issue
    like this?


    An attempt was made to access a pageable (or completely invalid) address at an
    interrupt request level (IRQL) that is too high. This is usually
    caused by drivers using improper addresses.
    If kernel debugger is available get stack backtrace.
    Arg1: 00000008, memory referenced
    Arg2: 00000002, IRQL
    Arg3: 00000000, value 0 = read operation, 1 = write operation
    Arg4: f724cc00, address which referenced memory

  2. Set a breakpoint in your MiniportSend[Packets]().
    Get the address of some Packet->Private->Head field.
    Set a "write access" breakpoint (trap) on that address.

    The breakoint should be hit when the packet's head pointer gets

    Can you provide an example of how to set a write access breakpoint in
    WindDbg? Thanks!

    It looks like the miniport is receiving the same packet twice before it
    returns the packet. The first time the miniport driver attempts to return
    the packet everything works fine, but then it tries to return it a second
    time because it received it twice, and then it crashes. What would cause it
    to receive the same packet multiple times?

  6. Is your miniport a serialized or a deserialized one? The return value
    of MiniportSend() and the 'Status' of each NDIS_PACKET for
    MiniportSendPackets() have a different meaning for serialized vs.

    You are probably somehow (and unwillingly) telling NDIS that you are
    already done with handling the packet although you are still handling

    This way, the protocol that sent the packet can re-use the packet
    while you are still handling it.
