The patch mentioned in posting # 76 is included in kernel 3.5-rc7, available
here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc7-quantal/
It would be good if someone with a 12.04 desktop edition could try this kernel
and comment.
Myself, I am not interested in what the 1 minute reported load average is, as
it will be all over the place.
I am intertested in the 15 minute load average, after about an hour.
Example "top" from my computer, where the 15 minute load average for 3
processes at 15 % each, 60 hertz sleep frequency used to be reported as about
2. Now it is about 0.46, which is correct:
top - 08:16:15 up 7:42, 3 users, load average: 0.14, 0.38, 0.46
Tasks: 134 total, 1 running, 133 sleeping, 0 stopped, 0 zombie
