== Runtime services accessing boot services memory ==
Many UEFI firmwarefirmwares have the issue of runtime services accessing boot services memory. There is a series of patches at https://lkml.org/lkml/2014/9/13/103 to detect these bugs without breaking systems.
(Trivia: https://lkml.org/lkml/2013/11/11/653, which uses a different approach, is written by HP that also locked access to firmware updates to paid customers not long afterwards)
