I tried the patch-2.6.7-spa_hydra_FULL-v4.0 patch
I only changed the value of /proc/sys/kernel/cpusched/mode to switch between

passed the 20 threads test:
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
