Bug Description
I started a new EC2 instance of Ubuntu 11.10 Oneiric using ami-a7f539ce in us-east-1.
About two days later, it became non-responsive to ssh, http, etc.
I found the following kernel oops stack trace in /var/log/syslog.
I stopped/started the instance to get it running again, so the attached reports may not be the exact hardware on which it failed.
