    initial v1  
    44I started with the same approach, inspecting the git log between hrev45225 ... hrev45681, identifying problematic patches, etc. - my list is even more complete than yours - but reverting them individually is in some cases problematic :-( I ended up with a kernel that didn't even boot, entering KDL early in the process. Reverting some patches created a lot of subtle fixup work in various places (e.g. removing B_RANDOMIZED_ANY_ADDRESS support..) which took a hour, and once it compiled and booted properly, I could still easily trigger the reboot.

    6 I decided to give up on this, and started again with reproducing the highly builds from 5 years ago, from an olde linux host system, by utilizing vanilla RHEL6 images in a singularity container, mimicking a standard host system for the cross-compilation from 2013.

    88I now have the btrev<XY> from 2013 running, and the old hrevs as well. By now, I successfully reproduced the random reboot with a self-compiled hrev5681. My bisect is currently at hrev45560, and this also does not produce random reboots.
