Sometime after 3PM PT on 3/1/2012, my instance (i-f2611ec2) became unavailable. Rebooting does not bring it back up. It is a Postgres-11.3.lucid-x86 appliance that had been running without a hitch for 40 days. I did not do any maintenance of any kind on it today. I accessed a Postgres database on this instance up to 3 PM PT today. I am attempting to stop the instance and then start, but the stop has been running for approximately 40 mins or more.
Checking the AWS console I see 2 of 2 status checks have failed.
The last entries from the console log (Plymouth command failed):

What else might I do to recover this instance?
