I've been seeing this too on a Sun X4100. What does attach is
acpi_throttle, which is completely useless unless I want a way to
quickly reboot the box:
cpu0: <ACPI CPU> on acpi0
acpi_throttle0: <ACPI CPU Throttling> on cpu0
powernow0: <Cool`n'Quiet K8> on cpu0
device_attach: powernow0 attach returned 6
Though I'm pretty sure I've seen both attach at once in the past.. well,
kinda sure. In /boot/loader.conf I have:
hint.acpi_perf.0.disabled="1"
hint.acpi_throttle.0.disabled="1"
But it seems to completely ignore it. The only thing I can think of
that might be causing it is that acpi is statically linked.
