A triple fault reboots the system in a pretty similar way to a transfer to real mode as a jump, so I'd imagine it works pretty well actually.

- amluto 4y agoOn a modern system, it resets a whole lot of things, including state that firmware expects to have initialized and various lock registers that can’t be unlocked without a reset. You can’t just run your system firmware kexec-style and expect it to work.
- monocasa 4y agoThat's fair. The last time I looked into the space of what happens on a reset on x86, hardware roots of trust were significantly less important to the point of not really being on my radar.
