We have Ubuntu 14.04 on 73 single socket machines, where one has this problem, and 3 dual socket machines where 2 have this problem. Problem machines: - single socket Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz, Supermicro X9DR3-F - dual socket Intel(R) Xeon(R) CPU E5520 @ 2.27GHz, Dell PowerEdge R710 - dual socket Intel(R) Xeon(R) CPU E5-2630 0 @ 2.30GHz, Supermicro X9DRFF-iG+/-7G+/-iTG+/-7TG+ (and the other dual socket one without the problem is another PowerEdge R710, strangely enough... maybe it's just not heavily loaded like the other, prime95 for a few hours doesn't cause it either) ** Affects: linux-lts-trusty (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1335091 Title: kernel BUG - handle_mm_fault - Ubuntu 14.04 kernel 3.13.0-29-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-trusty/+bug/1335091/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
