using 2.6.10-rc3-mm with Ingo's latest Real-Time Preempt on a pentium
M 1.6ghz laptop with a gig of ram. The test was done as a normal user
using the realtime-lsm patch and I have Rui's rtirq script up and
running. One of the three tests was completed while compiling gnuplot
in the background :).

I ran it 3 times. twice at 300s and once for 600 seconds. However I
dont think It actually ran for 5 minutes or 10 minutes. Every time I
ran it I got a similar warning/error (maybe I am supposed to get
this?)

 Also my context-switch rate is WAY higher than other folks. Am I
missing a tuning step?

over all I have been super happy with the latest ingo patch.
