And that's the one that bisected to the cr0/cr4 bits (and I did all my bisection on that because it's so much faster). Anyway, the kernel config itself is pretty simple. It's basically a F30 kernel config that has been through "make localmodconfig" and then pared down some more to remove stuff I don't use (paravirt etc). I would expect that if it's a confiuration difference, it's more likely to be about the user mode side - since the hang does seem to happen in user mode, not in the kernel (but a very early problem at cpu bringup time could easily have been hidden). On my laptop (which I am at right now), the hang is different, and maybe it's similar to your ACPI hang issue. I will try that revert, and at least see if that solves the laptop side. Linus
