We got a donation of a standard PC so we have now one publicly usable PC at the library. So I can take my time to try to make something out of the iMacs. Results: - 2023-06-18: ok - running strings on iso's vmlinuz yields 6.3.7-1 (2023-06-12) - 2023-11-16: fail - 6.5.10-1 (2023-11-03) As expected, the regression happened during the big gap between snapshots >_< Anything more I can test? (cross compiling old kernels is unfortunately too much over my head) It's weird that it seems the regression is about booting the iso. Otherwise, net installs from old iso like what Claudia did wouldn't work after rebooting after install. Cheers, -- tuxayo
