I just upgraded my Dell OptiPlex GX270 from RELENG_8 to RELENG_9. The machine no longer boots. However, if I put
in /boot/loader.conf then the machine runs fine. With RELENG_8 the machine had no loader.conf, and the power button worked on my desktop machine. Now with ACPI disabled my power button does not work. I have found that the machine hangs at boot during a scan of the PCI bus, but if I disable that (hw.acpi.disable=pci) then the machine cannot find a boot drive.
So I have lost functionality that worked fine in BSD 8.
