At last I think I can point at one single patch which would need to get applied to the kernel running as dom0 on Amazon EC2 hosts:
http://xenbits.xen.org/hg/staging/xen-3.1-testing.hg/rev/f1574ad9f702 I took the CentOS5.3 kernel, compiled it as a base for the comparison. Installed it as dom0 kernel and started an Oneiric domU with similar setup as t1.micro has. 3 out of 3 test runs would cause the multicall failure to show up. Next I applied the patch above (though I took the version from CentOS 5.4 source but it looks identical) and added it to the build. Then booted into the new dom0 kernel and now all three tests would successfully install the java-jdk. -- You received this bug notification because you are a member of OpenJDK, which is subscribed to openjdk-6 in Ubuntu. https://bugs.launchpad.net/bugs/634487 Title: t1.micro instance hangs when installing java Status in Release Notes for Ubuntu: Fix Released Status in “linux” package in Ubuntu: Confirmed Status in “linux-ec2” package in Ubuntu: Invalid Status in “openjdk-6” package in Ubuntu: Invalid Status in “sun-java6” package in Ubuntu: Invalid Status in “linux” source package in Lucid: Invalid Status in “linux-ec2” source package in Lucid: Confirmed Status in “openjdk-6” source package in Lucid: Invalid Status in “sun-java6” source package in Lucid: Invalid Status in “linux” source package in Maverick: Confirmed Status in “linux-ec2” source package in Maverick: Invalid Status in “openjdk-6” source package in Maverick: Invalid Status in “sun-java6” source package in Maverick: Invalid Status in “linux” source package in Natty: Confirmed Status in “linux-ec2” source package in Natty: Invalid Status in “openjdk-6” source package in Natty: Invalid Status in “sun-java6” source package in Natty: Invalid Bug description: Binary package hint: cloud-init I booted the 32bit EBS lucid AMI (ami-1234de7b) for a t1.micro instance.

I tried adding swap in case it was an out-of-memory condition, and it still repro'd.
