Rick, I was using a Xen guest with 8 cores and ~15G of memory. Host was a CentOs 5.(6 I believe) with Xen 3.4.3. But I also saw it happen when the same host runs Precise with Xen 4.1.2.
Stephen, now that is very interesting info. So if the kernel commandline would help but not the sysctl, that would narrow things down to the scheduler if any taskgroups exist and at least exclude the creation and destruction of new taskgroups. I should revisit the dump I got with that in mind. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1011792 Title: Kernel lockup running 3.0.0 and 3.2.0 on multiple EC2 instance types To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1011792/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
