I saw the same thing this morning. Ubuntu 14.04.2 LTS Kernel linux-image-3.16.0-30-generic libapache2-mod-apparmor 2.8.95~2430-0ubuntu5.1 apache2-mpm-prefork 2.4.7-1ubuntu4.4
Attached is first the warning (like in bug 1447530), and then the Oops, 9 seconds later. ** Attachment added: "warn and oops" https://bugs.launchpad.net/apparmor/+bug/1448912/+attachment/4402483/+files/both.txt ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1448912 Title: BUG: unable to handle kernel NULL pointer dereference (aa_label_merge) Status in AppArmor Linux application security framework: Confirmed Status in linux package in Ubuntu: New Bug description: I had a kernel problem with one of my high availability VMs. This was not the first occurence of the problem, it seems to appear every now and then. The VM froze because of the Kernel bug appended as a text file. I had to hard reset it. I am running Ubuntu 14.04.2 Kernel 3.16.0-34-generic with libapache2-mod-apparmor 2.8.95~2430-0ubuntu5.1 and apache 2.4.7-1ubuntu4.4 (mpm_prefork). Unfortunately I am unable to reproduce the bug at will. This is a serious problem for high availability VMs. Looking at the trace, I assume this is a bug in AppArmor.
