------- Comment From nevd...@us.ibm.com 2018-05-13 12:11 EDT------- This Canonical bug suggests they may have seen it before,but unfortunately it was closed without a patch because it wasn't repeatable in a later release. The bug suggests the change occurred between 4.4 and 4.6-rcsomething.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1580943 I did a git blame on rbtree.c and there were no interesting changes introduced during that time. I did the same with mmap.c and found many ... but none that claimed to be addressing this problem. Discussions here (https://lkml.org/lkml/2016/2/16/625) suggest it might be related to transparent huge pages (THP). Although none of this points to a specific solution, it does suggest this problem has been seen before. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1770784 Title: ISST-LTE:KVM:Ubuntu1804:BostonLC:boslcp4g4:ubuntu1604:P8 compat: guest crashes in apparmor_file_alloc_security() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1770784/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
