MmMapIoSpace(Size = 16GB)

Hi,

A remote deployment reveals that the system equipped with 16 GB RAM can map a BAR of 16GB size. Later on, a strange crash occurs. Is there a limit on MmMapIoSpace()? The OS is Windows 10 18362.1.amd64fre.19h1_release.190318-1202. Aside from a driver bug, how can MMIS() succeed in this context?

Regards,
Calin
