Alex,

I appreciate both your frustration and your desire to help, the Lucid
kernel has seen literally hundreds of patches since release (see
https://edge.launchpad.net/ubuntu/+source/linux/2.6.32-25.43) for just
the latest round of updates for the proposed kernel and more are already
on the way.

The linux task on this bug has not been closed, and is not being
ignored.  In general the kernel team tries to get bugs filed separately
and then merge them/mark them as duplicates after the fact.  This is
done, do to the nature of kernel bugs, where just because a bug has
similar symptoms they may not be related.  Eg. graphics issue on intel
hardware are most likely different than bugs on ati hardware, even if
they exhibit many of the same symptoms.

I asked that a new bug be opened, as the issues you are experiencing
seem to be different than the bug I had fixed, which specifically dealt
with a load calculation issue in the EC2 kernel, that is not present in
the -generic or -server kernels.  When this bug was opened it was
focused on EC2 which runs a kernel that is quite different than the rest
of Ubuntu, so generally bugs against EC2 are handled somewhat separately
from the rest of the Lucid kernel (this will change in the Maverick
kernel).

The fact is that there is more than one issue affecting load average on
Lucid, and dealing with them in one meta bug just isn't effective.  What
I wanted to do was split specific issues out so that they can be tracked
independently.  This is of course difficult to do when the bugs symptoms
are high load.

As per specific load problems, there are several issues that have
affected Lucid, and the upstream kernels (its not just Ubuntu).  There
have been the high number of wake ups from the load balancing tick,
there has been the write back issue, there is an update to how load is
computed from upstream that fixes a bug where load was under reported in
older kernels, all newer kernels have this patch and so it should be
expected that there are higher loads reported on newer kernels.

What isn't expected is spiraling out of control loads, extremely high
loads on an idle systems, or phantom loads.  We want to address all
issues.
