[Bug 513848] Re: [karmic] CPU load not being reported accurately

@tgabi:

I've uploaded a new test kernel to
http://people.canonical.com/~cndougla/513848/linux-
image-2.6.31-21-server_2.6.31-21.58~printk2_amd64.deb. This kernel will
print out each time the calc_load_tasks counter is changed between the
time each cpu increments it to represent the running processes to the
time the load avg is calculated. I'm guessing that on your server we
will see the counter incremented a few times and then decremented back
down to 0 by the time the load avg is calculated.

Please test this kernel by capturing the dmesg for a few minutes. We
don't need the dstat output for this anymore, since we know the load avg
is being calculated correctly from the calc_load_tasks value. Attach the
dmesg here and we'll take a look.

Thanks
