Thomas,

> We are pleased to announce the 2.6.24.7-rt15 tree [..]
Looks like this newest is also our greatest:

Board: Core 2 Duo, 2.4 GHz, Intel G965, 64 bit
Kernel: 2.6.24.7-rt15 prerelease
Config: CONFIG_IRQSOFF_TRACER, CONFIG_PREEMPT_TRACER, CONFIG_FTRACE
Stress: hackbench 25 loop, ls -Ral / loop, flood ping from outside
On-demand cpufreq disabled:
# cd /sys/devices/system/cpu
# echo performance >cpu0/cpufreq/scaling_governor
# echo performance >cpu1/cpufreq/scaling_governor
Test: cyclictest -a -t -n -p99 -i100 -d50
Result:
560.44 586.11 606.12 211/1160 3727
T: 0 (18617) P:99 I:100 C:1011846111 Min:  2 Act:  4 Avg:  5 Max: 39
T: 1 (18618) P:98 I:150 C: 708641019 Min:  2 Act:  5 Avg: 11 Max: 57

While running more than one billion cyclictest loops, the internal
worst-case latency did not exceed 39 microseconds.


Great work, thanks a lot!
