Date: Thu, 19 Aug 2010 15:16:53 +0000 I can re-afirm this bug with 8.1-RELEASE on the system mentioned before and also on a second system. The second system uses this CPU: %dmesg | grep -i amd [email protected]:/usr/obj/usr/src/sys/GENERIC amd64 CPU: AMD Athlon(tm) II X2 240e Processor (2800.01-MHz K8-class CPU) Origin = "AuthenticAMD" Id = 0x100f62 Family = 10 Model = 6 Stepping = 2 AMD Features=0xee500800<SYSCALL,NX,MMX+,FFXSR,Page1GB,RDTSCP,LM,3DNow! +,3DNow!> AMD Features2=0x37ff<LAHF,CMP,SVM,ExtAPIC,CR8,ABM,SSE4A,MAS,Prefetch,OSVW,IBS,SKINIT,WDT> The levels look correct: %sysctl dev.cpu.0.freq dev.cpu.0.freq_levels dev.cpu.0.freq: 800 dev.cpu.0.freq_levels: 2800/22790 2450/19941 2100/16660 1837/14577 1600/13837 1400/12107 1200/10377 1000/8648 800/6200 700/5425 600/4650 500/3875 400/3100 300/2325 200/1550 100/775 There is no speed-stepping detected: %dmesg -a|egrep '^est[0-9]*' % Both mainboards are from Sapphire and both systems run amd64. Using the x86 version of FreeBSD solves the problem, i.e. I do get est devices and C2/C3-states!!! But this is not an option because of memory requirements. As this bug is marked as feedback, please let me know what I can do to help get this issue fixed.
