Yes, I've seen it. And you need to check that memory above 4GiB is mapped at
all before you can use them. For this you need to read cr3 and parse page
mapping and if needed error out or add missing mapping.
Additionally buffers for disk reads and other hardware-related tasks need to
be under 4 GiB.
