Thanks for your review.
An updated version of test and change is attached to the bug [1].
With my crosstest exe this testbot run was started [2].

I tried to run the test in a 64bit VM but got just blue screens with 
MULTIPLE_IRP_COMPLETE_REQUESTS.
Are the driver test framework patches supposed to succeed on 64bit windows?

Kind regards,
Bernhard
