Currently also encountering this issue (the same kernel panic) with ami- 3079f543 on eu-west-1 with a c3.large instance.
So this seems to be a general ubuntu 16.04 on AWS issue and not an upgrade specific issue. I haven't seen this issue with the beta2 AMIs. Interestingly I seem to be able to start the AMI on t2.micro instances, so this could well be instance type specific. ** Attachment added: "AWS Kernel panic log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1573231/+attachment/4648152/+files/aws.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573231 Title: Kernel Panic on EC2 After Upgrading from 14.04 to 16.04 via do- release-upgrade -d To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1573231/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
