Hi,
is the backtrace always the same, especially the apparmor part, or are there
differences? It looks like it just does a kzalloc(), but perhaps there's e.g.
some double freeing that corrupts SL*B structures.
Can you provide your .config? Now we don't even know if it's SLAB or SLUB.
Also could you run the oopses through this script?
