Just a comment from a security module developer. What happens if you pass security=none to kernel command line options (i.e. disable AppArmor security module), for I think it might help isolating the problem because you are hitting oops at security_vm_enough_memory_mm() and security_file_free().
Also, can you afford try compiling the kernel with KASAN enabled (i.e. CONFIG_KASAN=y), for it might be some memory corruption error (including possibility of use-after-free bug) ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1720263 Title: BUG: unable to handle kernel paging request at ffffffffffffffe1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1720263/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
