I have problems in cpufreq in RELENG_6 (today).
I try to set another frequency in my laptop and get this error:
# sysctl dev.cpu.0.freq=250
dev.cpu.0.freq: 2000
sysctl: dev.cpu.0.freq: Device busy
Some information below...
# sysctl -a | grep freq
...
debug.cpufreq.lowest: 0
debug.cpufreq.verbose: 8
machdep.acpi_timer_freq: 3579545
machdep.tsc_freq: 1995011972

dev.cpu.0.freq_levels: 2000/22000 1750/19250 1500/16500 1250/13750

3750/-1 2500/-1 1250/-1
I set debug.cpufreq.verbose=8 and get some messages, dmesg attached.
pciconf are attached too.
Another problem are in kldunload and cpufreq. Does not work. Message below.
# kldstat
Id Refs Address Size Name
1 2 0xc0400000 4b9a28 kernel
2 1 0xc2c49000 8000 cpufreq.ko
# kldunload -v cpufreq
Unloading cpufreq.ko, id=2
kldunload: can't unload file: Device not configured
Thanks
