Also relevant: https://xkcd.com/927/ UEFI has gone through a number of revisions over the years, and has optional bits like Secure Boot (which itself has gone through revisions). Almost any set of standards has undefined corners where vendors interpret things differently. Vendors also have bugs in weird places sometimes. The firmware and boot loaders arguably are the least "exercised" parts of a system - both change rarely and there are few implementations. There's not many combinations, and they don't change a lot. I'm interested to read about the cause of this issue - something like this can be a lesson on "hmm, hadn't thought of that before" type things to watch for in other areas. -- Chris Adams <linux at cmadams.net>
