I am using FreeBSD 8 with ZFS and I am very happy with it. Performance and featureset is the best I have seen around. With the exceptions of one thing... Power management doesn't work on my system. I have an Asus M4N78-VM board with an AMD 240e CPU and I can't get the system to suspend and resume. This is important for me, because I want to access my system at any time, but most of the time it doesn't do anything.
Now it uses 70W when idle and I would like to lower this. I had no success on the ACPI mailinglist, but I wondered if ACPI support is better with an i386 kernel. Can anyone comment on that and can I switch back to an i386 kernel on an already installed AMD64 environment. I only have 2GB, so AMD64 doesn't have a lot of advantage on my system.
