Rick, I always thought that page faults and time in the dispatcher were recorded for the TCB or SRB that incurred the time. I'm not aware of a page fault in a TCB handing off to an SRB.
I'm know I'm a storage guy, but this is counter to most of what I have been taught about attribution of CPU Time over the years.
