Here are my results on Intel Pentium 4 :

Command line :  ./cyclictest -t 1 -p 80 -i 10000 -l 10000 -q

Can you post the output of /proc/timer_list?

The output of /sys/devices/system/clocksource/clocksource0/available_clocksource
and a full boot log are more interesting.

2.6.23-rc8-rt1 :

That one should give you sane results.

Those results _are_ sane for a non high resolution timer kernel.

CONFIG_HIGH_RES_TIMERS=y are defined in .config then why I am getting
"WARNING: High resolution timers not available".

We need to look at the information I requested above. I'm not good in
witchcraft :)
