.pagein never works (for me)

Hi, let's say I'm inspecting a process and found this:

THREAD ffffd6097211a700  Cid 0edc.0f40  Teb: 000000551979e000 Win32Thread: ffffd6095dbc7080 WAIT: (WrUserRequest) UserMode Non-Alertable

and running !thread shows:

!thread ffffd6097211a700  
Unable to get field ReservedForNtRpc of type TEB at 0xffffd6097211a700

I try, without success things like:

.pagein /f /p ffffd60971c66540 ffff86047ae16000

using kernel and user mode stack area addresses (the latter obtained in TEB) but pages are not loaded after the g command.

Is there some OS settings I'm forgetting to check or some extra task I'm missing?

Thanks,
Mauro.
