#regzbot introduced v6.7.5..v6.7.6
I'm experiencing an issue where kexec does a full firmware reboot instead of kexec reboot.
Does mainline show the same problem? The answer determines who later will have to look into this.
Issue first submitted at OpenSuse bugzilla [0].
OS details as follows: Distributor ID: openSUSE Description: openSUSE Tumbleweed-Slowroll Release: 20240213
Issue has been reproduced by building kernel from source.
kexec works as expected in kernel v6.7.5. kexec does full firmware reboot in kernel v6.7.6.
I followed the docs here [1] to perform git bisect and find the culprit, hope it's alright as I'm quite out of my depth here.
With a bit of luck somebody might have heard about problems like yours. But if nobody comes up with an idea up within a few days we almost certainly need a bisection to get down to the root of the problem.
I'm working on a more detailed guide describing the process, maybe that works better for you:

It among other will make you check mainline and also 6.7.7, which was just released.
