Hello,
I'm building a new system with an AMD Phenom 9350e Quad-Core:
FreeBSD phenom.example.net 7.1-PRERELEASE FreeBSD 7.1-PRERELEASE #0:
Tue Aug 26 19:49:24 UTC 2008 root@phenom.example.net:/usr/obj/usr/\
src/sys/GENERIC i386
Everything's running smoothly, until I start powerd. As soon as
that happens, the system freezes hard. Trying powerd in the foreground
with -v shows that it decreased the frequencies a few times, but then
hangs the system.
So I've tried this manually:
# sysctl dev.cpu.0.freq_levels
dev.cpu.0.freq_levels: 1985/-1 1736/-1 1488/-1 1240/-1 992/-1 744/-1
496/-1 248/-1
# sysctl dev.cpu.0.freq
dev.cpu.0.freq: 1985
powerd freezed the system after reaching 1240 when trying 992. If I set
the frequency manually down to 1240 with:
# sysctl dev.cpu.0.freq=1240
everything's fine. But as soon as I try setting it further down
(992, 744, 496 or 248), the system freezes too, just the same
as with powerd. This is 100% reproducible.
So what's going on here?
Thanks,
-cpghost.
Oh, here's dmesg, if it helps:
