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).
