--- Comment #4 from Zebediah Figura  ---
The bug isn't actually with IoGetDeviceObjectPointer (at least for Tages), but
rather with MmMapLockedPagesSpecifyCache() returning a NULL pointer:

29be:    ff 15 38 1f 01 00       call    [00011F38h]    ;
<MmMapLockedPagesSpecifyCache>
    29c4:    50                      push    eax
    29c5:    56                      push    esi
    29c6:    e8 35 d9 ff ff          call    0300

300:    83 ec 30                sub    esp, 30h
...
     3bd:    8b 44 24 38             mov    eax, [esp+38h]
     3c1:    66 c7 00 05 00          mov    word [eax], 0005h
