Re: PROBLEM: Unusually high load average when idle in 2.6.35, 2.6.35.1 and later

[tmhikaru]

	These final tests I think conclusively prove that I've been on a
wild goose chase. The load average statistic is indeed broken somehow, and I
did bisect it down to where the problem began, however there seems to be no
performance problem related to it I can find. Somehow I must have made a
mistake I didn't catch when I did the original build that led me to believe
on top of the statistic being broken, that it was causing a performance
problem.

	All of the make allnoconfig test results finish within a second of
eachother, with four different kernels tested. I think if there really was a
performance problem it would have reared its head sometime during the
multiple compile tests on different kernels I took. I apologize for wasting
everyones time, especially my own :)

Anyway, the results:

2.6.35.6:
