Stefan, Which commit has the race condition comment? I'm aware of a problem with SUSE's kernel with regard to PV ticketlocks and HYPERVISOR_poll(), but I don't see any mention in upstream 3.2.x or XenLinux 2.6.18.
Your 10.04 2.6.32-era kernel doesn't have ticketlocks, so the underlying hypervisor version should not be a factor. But for the sake of argument, the lockups are observed on Xen hypervisors newer than 3.2. What are you using for upstream Xen components for 2.6.32? Is it the SUSE tree? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/929941 Title: Kernel deadlock in scheduler on m2.{2,4}xlarge EC2 instance To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-ec2/+bug/929941/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
