I see the same thing. I'd been running -CURRENT on this box for around 18 months, and decided to reinstall with a fresh JPSNAP (20030506) this morning, since things had gotten messy. Even after a full rebuild of world/kernel, things are quite slow and unresponsive. No fancy flags or anything passed to GCC. I also see the ACPI complaints in dmesg. My last world/kernel was from April 20, at which point performance was quite decent (relative to other points in the 5.x series). -- Munish Chopra
