Bug Check 0x44: MULTIPLE_IRP_COMPLETE_REQUESTS

Given that the storage stack generally works correctly, my guess is that
you have mismanaged an IRP in your new and therefore buggy driver and
that classpnp is a victim of this mismanagement as the IRP in question
is recycled from network to storage stacks.

Have you tried reproducing the failure with driver verifier enabled for
at least your driver?
