Kerneloops
With the Ubuntu 9.04 Beta release, we invite you to install and test the kerneloops package. kerneloops is a daemon that collects kernel crash information and then submits the extracted signature to the kerneloops.org website for statistical analysis and presentation to the Linux kernel developers.
