Hi

I tried this on the latest staircase patch (7.I) and am not getting any 
output from your script when tested up to 60 threads on my hardware. Can you 
try this version of staircase please?

There are 7.I patches against 2.6.8-rc4 and 2.6.8-rc4-mm1

http://ck.kolivas.org/patches/2.6/2.6.8/

Cheers,
Con
