CPU s.l.o.w.

Hi,

Im installing Duke 2007.05 on a Thinkpad R50e. Everything seemed to be going swimmingly until I downloaded emacs_cvs from AUR and ran makepkg. 10 hours later it is still compiling .el files to .elc.

According to top, the CPU is spending 0-1% of time in userspace, and 99-100% of time idling.
According to cpufreq-info (with "conservative" governor), the CPU is at its minimum 800MHz (max is 1.7G).
Throughout all this time the fan has never roused itself above a gentle breeze.

Why is the CPU not applying itself fully to the task at hand?

I can use FIrefox with no apparent sluggishness; and in the first minute of makepkg I caught cpufreq-info at 1.4GHz.

I'm stumped. What am I missing? Does anyone have any ideas?

Ta.

PS:

in rc.conf:
MODULES = (e100 eepro100 mii ac97_bus snd-mixer-oss snd-pcm-oss snd-page-alloc snd-pcm snd-timer snd snd-ac97-codec snd-intel8x0m soundcore !speedstep_centrino ibm_acpi fan acpi-cpufreq cpufreq-ondemand cpufreq_stats cpufreq_userspace)

DAEMONS = (syslog-ng network netfs crond acpid powernowd powersave cpufreq)

PROGRESS:
Installing cpufreqd fixed the freqency problem (whoops), but the system still seems to be sleepwalking:

/proc/acpi/processor/CPU/power

says:

active state:            C3
max_cstate:              C8

Does anyone have any ideas on how to change this?

Fixed !
The hostname in my /etc/hosts (localhost@localdomain) did not match the host name in my /etc/rc.conf. When I corrected this, bootstrap-emacs came to life.

Re: CPU s.l.o.w.

I'm having a somewhat similar problem in that I cannot get the CPU to max out.  It is a 1.73ghz pentium m.  If i put it into "performance mode", the max it seems to go is 1333mhz.  How can I get it to actually use what it has?
