Re: DMA transactions

can you post a callstack and the results of !analyze for the crash when you
call WdfDmaTransactionCompletedFinal?

In that case, I wonder why it crashes when I call

WdfDmaTransactionCompletedFinal

but does not when I call

WdfDmaTransactionRelease followed by WdfObjectDelete...

Once you have started the transaction by calling
WdfDmaTransactionExecute, you must call WdfDmaTransactionCompletedXxx or
WdfTransactionRelease before deleting it.

WdfTransactionRelease is required only if you are planning to reuse the
transaction object for another transfer.
