Bug Description
Currently there are some questions about the process used in creating EBS mounts. It's also unclear whether a server survives a reboot after an EBS has been mounted. This is possibly a known issue with EC2/EBS, but we should investigate.
I just set up a server, mounted EBS, attempted a reboot, and found the instance to be unresponsive.
