In point of fact, VT-d is disabled by default; you need to explicitly enable it
for it to use memory.  However, it's possible that there's a bug, or some other
change caused the memory difference, so it's worthwhile to try and track it down
a little better.  In particular, you jumped from the 5.2 kernel to the 5.4, so
it would be worthwhile to try the 5.3 kernel and see what you get.
