This is a general request for some testing help for Ubuntu 10.04 (Lucid) on ec2. If there are other problem reports about strange process cpu times or hangs without any message it would be good to pass this on. Trying to pull in a wide range of upstream fixes, I have prepared linux-ec2 packages that include all the fixes to Xen code which could be found in other places. This is quite a big change, so while I have successfully booted the test kernels on various ec2 instances, this usually does not really provide much insight about what happens when facing more or less real workloads. So anybody who is willing and able to help testing would be highly welcome.
The kernel packages are at: http://people.canonical.com/~smb/lucid-ec2-ng/ To use those, http://uec-images.ubuntu.com/lucid/current/ has current AMIs and using --kernel with a matching AKI from https://lists.ubuntu.com/archives/ubuntu-cloud/2010-December/000466.html will use pv-grub for booting. So the new kernel can just be installed via dpkg and activated by rebooting. Please report back anything that seems to be worse or better than before.
