Another update, two things this time:

1. I now also tested with a R10K equipped Octane (both dual 195 and single 250 MHz processors) and I didn't observe any problems there during bootup. So it could indeed be a problem specific for IP28 with 7.2 kernel (as said, with 7.1 bootup was fine, see this dmesg).
   
2. I did manage to get segfaults for the R10K Indigo² in single user mode, too, now, after some fiddling. I don't yet recognize a systematic here unfortunately. But my initial assumption, that this would only affect multi-user mode, hence was wrong.
   

You can also sign up for gitea and post patches there if you prefer to keep it within our community. It's entirely up to you

Actually I'd like to keep this on GitHub, also because my other stuff is all there. But if people want to fork it here, that's cool, too. Just make sure to create PRs on GitHub for any changes you want to be added there.
