State-Changed-From-To: feedback->open
State-Changed-By: arundel
State-Changed-When: Sat Feb 19 14:06:09 UTC 2011
State-Changed-Why: 
I can still reproduce this issue in a very recent HEAD (9.0):

otaku% sysctl dev.cpu
dev.cpu.0.%desc: ACPI CPU
dev.cpu.0.%driver: cpu
dev.cpu.0.%location: handle=\_PR_.CPU0
dev.cpu.0.%pnpinfo: _HID=none _UID=0
dev.cpu.0.%parent: acpi0
dev.cpu.0.temperature: 34,0C
dev.cpu.0.freq_levels: 1800/-1 1575/-1 1350/-1 1125/-1 900/-1 675/-1 450/-1 225/-1
dev.cpu.0.cx_supported: C1/0
dev.cpu.0.cx_lowest: C1
dev.cpu.0.cx_usage: 100.00% last 470us
dev.cpu.1.%desc: ACPI CPU
dev.cpu.1.%driver: cpu
dev.cpu.1.%location: handle=\_PR_.CPU1
dev.cpu.1.%pnpinfo: _HID=none _UID=0
dev.cpu.1.%parent: acpi0
dev.cpu.1.temperature: 35,0C
dev.cpu.1.cx_supported: C1/0
dev.cpu.1.cx_lowest: C1
dev.cpu.1.cx_usage: 100.00% last 1033us

...dev.cpu.%d.freq is *missing*. During reboot/shutdown i get a warning that
dev.cpu.0.freq is not available (i think issued by powerd).
