Aaron, yeah, I was talking about CBMEM_FSP_HOB_PTR. Obviously if that
gets corrupted, things are going to be ugly. Since Ben was talking
about the stack getting corrupted during CAR migration, That's what I
was thinking might be happening. Maybe it wasn't getting saved
anymore, maybe it was getting overwritten, heck, maybe the new FSP was
returning the pointer differently.
Your solution is probably correct though. Thanks.
