[Bug 1448912] Re: BUG: unable to handle kernel NULL pointer dereference (aa_label_merge)
I've marked the releases which have went end-of-life as "Won't Fix".

apport information ** Tags added: apport-collected trusty ** Description changed: 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.
