The last successfully booting system for me is hrev58067. I am not using the dedicated R5 testing so I didn’t put this in that thread. Do I need to make a bug? Is this enough information?
OK, so looking at that ticket I’m not sure if it’s the same or not. If I disable ACPI I can boot fine, the person who opened that ticket still has the same issue if they do that. Anyway I’m not really sure if I have enough info to make opening a bug worthwhile. I’ll wait for that one to get resolved and see if it fixes mine.
We’ve tracked this regression to a recent ACPI change. It’s not a change that was merged into the beta5 branch, though, so it’s not going to hold up the release, at least.
