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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/634487 Title: t1.micro instance hangs when installing java To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/634487/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
