Yes, as you mentioned, there are only two difference. When I meet the bug, I have no idea to deal with it. So I try several method and times to fix it. After I changed the code up to the patch as I send to you, it works fine. And till now I am not very such whether this bug has been fixed. So I this patch just a try and I cannot explain it exactly even today.That patch appears to be to your wdf version of the code... can you give me a summary of what the change you made is? At a guess, the difference to the original code is that you are doing two separate notify's, and a KeMemoryBarrier after each. Can you tell my why the barrier is required? I just noticed that the for() loop will never actually do anything as req->nr_segments is initialised to zero... that's the same in my current code too! I wonder how long that has been a problem for? I'll change my code to initialise nr_segments to the maximum.
