Wild guess: I think acpi is no longer built as module on recent -CURRENT but included in the kernel. Perhaps the unload dance you did above "fixed" the double loading of the module? Could you check if your nextboot kernel is containing/missing ACPI directly? Cheers, Ulrich Spoerlein PS: I'm not saying ACPI code is at fault, but rather loader code that loads the modules -- It is better to remain silent and be thought a fool, than to speak, and remove all doubt.
