Broken UEFI implementations: Difference between revisions

Acer for some reason don't honor the BootOrder variable under most conditions. This has been an ongoing issue forever, chronicled most recently here: https://github.com/rhinstaller/efibootmgr/issues/19

 

Many UEFI firmwares 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)
