These two commits are very self contained, arch specific, and obviously safe as they only add memory barriers. Will apply for Utopic and submit for Trusty. ** Changed in: linux (Ubuntu) Assignee: (unassigned) = Andy Whitcroft (apw) ** Changed in: linux (Ubuntu Trusty) Assignee: (unassigned) = Andy Whitcroft (apw) ** Changed in: linux (Ubuntu) Importance: Undecided = High ** Changed in: linux (Ubuntu Trusty) Importance: Undecided = High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1358569 Title: ppc64le oopses and userspace process hangs in System V semaphore code To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1358569/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Looks like we also want these commits to fully support backporting this to trusty and pick up all the spinlock fixes in one go: 919fc6e34831d1c2b58bfb5ae261dc3facc9b269 3405d230b374b6923878b21b8d708d7db1f734ef 7179ba52889bef7e5e23f72908270e1ab2b7fc6f -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1358569 Title: ppc64le oopses and userspace process hangs in System V semaphore code To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1358569/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Ok I have backported those 5 commits to trusty and built a test kernel for testing. The kernel is at the URL below. Pleas report any testing back here: http://people.canonical.com/~apw/lp1358569-trusty/ The individual patches are also split out at the above URL and I am attaching the overall diff. ** Patch added: COMBO.diff https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1358569/+attachment/4181441/+files/COMBO.diff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1358569 Title: ppc64le oopses and userspace process hangs in System V semaphore code To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1358569/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

For the record, this hits the buildds and kills them occasionally, so we should definitely get this into both utopic and trusty. ** Changed in: linux (Ubuntu) Status: Incomplete = Confirmed ** Changed in: linux (Ubuntu Trusty) Status: Incomplete = Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1358569 Title: ppc64le oopses and userspace process hangs in System V semaphore code To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1358569/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
