Same here. Running with
debug.cpufreq.lowest="1240"
in /boot/loader.conf to prevent freezes.
This is a FreeBSD 7.1-PRERELEASE #0: Sat Nov 8 14:18:05 CET 2008
root@textbox:/usr/obj/usr/src/sys/GENERIC
running in amd64 and i386 mode with ACPI enabled (default):
CPU: AMD Phenom(tm) 9350e Quad-Core Processor (2000.08-MHz K8-class CPU)
Origin = "AuthenticAMD" Id = 0x100f23 Stepping = 3
Features=0x178bfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,
PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,MMX,FXSR,SSE,SSE2,HTT>
Features2=0x802009<SSE3,MON,CX16,<b23>>
AMD Features=0xee500800<SYSCALL,NX,MMX+,FFXSR,Page1GB,RDTSCP,LM,
3DNow!+,3DNow!>
AMD Features2=0x7ff<LAHF,CMP,SVM,ExtAPIC,CR8,<b5>,<b6>,<b7>,
Prefetch,<b9>,<b10>>
Cores per package: 4
using an MSI board with SB600 chipset and newest BIOS.
No idea why the system freezes below approx 1200 MHz. But apparently,
this bug is quite common and affects a lot of systems with Phenoms. :(
