Well, works. Thanks. It's possible to printf some message about this if
kern.timecounter.hardware != ACPI-fast? Or add message in cpufreq(4)?
Thanks

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
Timecounter "TSC" frequency 1995011972 Hz quality 800
Timecounters tick every 1.000 msec
Try setting your timecounter to acpi or i8254 (not TSC):
sysctl kern.timecounter.hardware="acpi"
Without complicated recalibration code (which no one has written yet),
we can't base our system time off the TSC counter when cpufreq is
changing it.
