Might be that the other machine has its 2.6.22 version of .config messed

machine seems to have gone down for the count, but without me torturing
it...
Also, keep in mind that various stages can "record" a memory misordering,
for example, by incrementing the wrong counter.
The other machine not only booted, but has survived several minutes of
rcutorture thus far. I am also trying POWER5 machine as well, as the
one currently running is a POWER4, which is a bit less aggressive about
memory reordering than is the POWER5.
Even if they pass, I refuse to reduce GP_STAGES until proven safe.
Trust me, you -don't- want to be unwittingly making use of a subtely
busted RCU implementation!!!
Thanx, Paul
