It does seem odd, the resource isn't DISCARDABLE.
It is actually the KsLoadResource that faults while looking for the
resource, the pointer looks like its about 0x400 away from the
imagebase. If I load the resource, then store the resources pointer
that pointer won't throw an access violation and seems to work just fine.

What is interesting is that the same KsLoadResource will throw an
access violation if you store DriverStart and use it later inside a
function like NewStream running at PASSIVE_LEVEL.
Really? I'm surprised by that. I could understand it at
DISPATCH_LEVEL, because the resource segment is probably marked as
pageable.
Is the resource marked as DISCARDABLE?
