Comment 3 for bug 566793

@Scott: The command is supposed to return the last 64K of console
output. Your results are expected in that case. See the first note
from: http://docs.amazonwebservices.com/AWSEC2/latest/DeveloperGuide/index.html?instance-console.html

As for the time, it should be timing out after 20 seconds -- are you
not seeing that behaviour?
