Comment 12 for bug 686692

I'm still unable to boot i386 instances. I tested
  us-east-1 ami-5c3fcf35 canonical ebs/ubuntu-natty-daily-i386-server-20110131
It resulted in no console output and unreachable instance in t1.micro.

So, i386 is still broken on t1.micro (the same ami does boot on m1.small).

However, x86_64 is functional. I just verified
us-east-1 ami-2e3fcf47 canonical ebs/ubuntu-natty-daily-amd64-server-20110131

$ uname -r
2.6.38-1-virtual
$ uname -m
x86_64
$ ec2metadata --instance-type
t1.micro
$ dpkg -S /boot/vmlinuz-$(uname -r)
linux-image-2.6.38-1-virtual: /boot/vmlinuz-2.6.38-1-virtual
