I've just done 2 things:
a.) verified this bug is present in natty at vmlinuz-2.6.38-2-virtual
b.) some task editing.
The task editing was mostly to just tag which releases this affects. Basically:
linux-ec2: lucid
linux-virtual: maverick, natty
Any other tasks can be closed as 'invalid' or
Even with the workaround, the resulting java install appears somewhat
unstable and will die with the same error at random times. Using 32bit

One downside I discovered by using this solution (stop the instance -
make it a small - update java - stop it again - modify it back to micro)
is that the new instances start with new private ips. That means that

t1.micro instance hangs when installing sun
Hi all,
I did what Daniel suggested:
Launch the instance as m1.small, then install java, and save as a different
ami. From then, you can launch the saved ami as t1.micro.
but after that I was unable to connect to newly launched instance. The error I
get is connection refused.
I tried with the

As an additional FYI, I've received this exact same error in a running
instance. That is, it not only happens during a java install. Java had
already been installed and running fine, and then this error occurred
while running the Jetty app server.

Same thing on 32bit Lucid.
I tried to disable IPv6
sudo mv /lib/modules/2.6.32-308-ec2/kernel/net/ipv6{,.off}
because i saw references to it in the segfault message in the console log,
but it didnt make any change.

Im a new EC2 user and have just come across this.
How do I start a t.micro instance as m1.small and retain the root volume
Im using in the t.micro instance ?
I have installed other apps and have configuration and now find I need
to change from openjdk to sun-java6-jdk. I dont want to have to go
ultan,
ec2-stop-instance ${IID}
ec2-modify-instance-attribute --instance-type m1.small ${IID}
ec2-start-instances ${IID}
ssh to instance and do whatever you want
ec2-stop-instance ${IID}
ec2-modify-instance-attribute --instance-type t1.micro ${IID}
ec2-start-instances ${IID}

The workaround is only useful when you're setting up a new instance.

Thanks Scott. It didn't occur to me to try switching my instance to small,
do the install, and then switch back to micro. I'll give that a try.
Also, for some reason I thought the amd64 builds of Ubuntu were lacking in
some components. Maybe that's only true for client, but I definitely saw a
Thanks all for the workaround, I've tried it on several of my instances

@DanielDaniel, Branden,
The easiest work around is
a.) start the instance as m1.small or m1.large (depending on if you want i386
or x86_64).
b.) install java
c.) stop the instance (ec2-stop-instances or /sbin/halt from inside the
instance)
d.) modify the instance to be t1.micro
I believe you can install java fine on a t1.micro x86_64 this bug only

I've done some more testing/poking and here's what I've found:
suite___ |arch| java___ | result
lucid___ |32 |sun-java6-jdk | fail, system unreachable
lucid___ |32 |openjdk-6-jdk | fail, system unreachable
maverick |32 |sun-java6-jdk | bad performance, dpkg hang
maverick |32 |openjdk-6-jdk |
The failing code is identical in Lucid and Maverick, so I'm thinking the
difference between the two is that the Lucid fault occurs on a kernel
page, which is fatal, while the Maverick failure occurs on a user page,
which kills the process but not the kernel.

Linux takes a page fault, and in the process of updating the page tables to map
