hello,
yet another powerd SOS : on an ASUS M3A78-EM MB with
Phenom 9750 and 8 gig memory, starting powerd freezes
the box after slowing down a bit cpu frequency.
[IMHO] usefull bit of info :

further :
- I set debug.cpufreq.lowest superior to 1500 : system remains
up but only when pushing really slightly
- I set debug.cpufreq.lowest inferior to 1100 : freeze
garantueed
- I define hint.acpi_throttle.0.disabled="1" in loader.conf
then no dev.cpu.0.freq is showing up ... (as if
only acpi_throttle is attaching and not powernow)
Let me know what I can test further.
Best, Arno
