Manually installing the latest kernel from Karmic Koala also acts as a
fix for the problems, which is pretty much a smoking gun pointing at the
kernel shipped with Lucid Lynx, in my opinion!

Adding a link to linux-image as this does not just affect EC2.
I have a decent number of HP ProLiant systems and about 90% are
exhibiting the exact same problems. All of the systems affected have a
load average between 0.7 and 1.1 just a short while after being
rebooted, and are 100% idle.

Load issue from #6 and #7 look like the same. Running ext3 on

shooting up, during code builds, but not always. Sometimes builds would
proceed normally. Also random load/hang during normal non-busy server
activity. My first thou
Matthew are the "mystery" disk io load you mention in #7 the same as you
describe in #6? In #6 what else are you running on the machine? Do you
have additional instances running. Another possibility is what
filesystems are you using on the host and instance.

Related or not to this bug, I've had to revert to Karmic on EC2 due to
"mystery"(looks disk io related, but i can't see it with
vmstat/iostat/etc) load on Lucid. Having reverted, load is gone.

I have been able to replicate this, and actually watch the load averages
fluctuate on an idle system. I have begun investigating and hope to
have a solution soon.
