My Dell Latitude D600 seems to be reporting wrong cpu-speed. The dmesg says acpicpu0 at acpi0: C3, C3, C2, C1, FVS, 1600, 1600, 1400, 1200, 1000, 800, 600 M Hz
which I believe to be correct. But this is what I get from sysctl hw.cpuspeed=600 hw.setperf=100 Changing hw.setperf makes no difference hw.cpuspeed=600 hw.setperf=50 Any ideas what might be wrong here? /Markus $ sysctl hw hw.machine=i386 hw.model=Intel(R) Pentium(R) M processor 1600MHz ("GenuineIntel" 686- class) hw.ncpu=1 hw.byteorder=1234 hw.pagesize=4096 hw.disknames=wd0,cd0 hw.diskcount=2 hw.sensors.acpitz0.temp0=33.55 degC (zone temperature) hw.sensors.acpiac0.indicator0=On (power supply) hw.cpuspeed=600 hw.setperf=100 hw.vendor=Dell Computer Corporation hw.product=Latitude D600 hw.serialno=1T8W01J hw.uuid=44454c4c-5400-1038-8057-b1c04f30314a hw.physmem=536104960 hw.usermem=536092672 OpenBSD 4.4-beta (GENERIC) #1: Mon Jul 21 20:21:23 CEST 2008 [EMAIL PROTECTED]:/usr/src/sys/arch/i386/compile/GENERIC cpu0: Intel(R) Pentium(R) M processor 1600MHz ("GenuineIntel" 686- class) 1.60 GHz cpu0: FPU,V86,DE,PSE,TSC,MSR,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,PAT,CFLUSH, DS,ACPI,MMX,FXSR,SSE,SSE2,TM,SBF,EST,TM2 real mem = 536104960 (511MB) avail mem = 510164992 (486MB) mainbus0 at root bios0 at mainbus0: AT/286+ BIOS, date 12/15/03, BIOS32 rev. 0 @ 0xffe90, SMBIOS rev. 2.3 @ 0xf8cc0 (62 entries) bios0: vendor Dell Computer Corporation version "A09" date 12/15/2003 bios0: Dell Computer Corporation Latitude D600 acpi0 at bios0: rev 0 acpi0: tables DSDT FACP ASF!
