Memory corruption - can it be blamed on network code?

I am experiencing a memory corruption since 2.6.35-rc6 that involves the intel i915 driver (but now might implicate network code as well). It is being tracked at https://bugs.freedesktop.org/show_bug.cgi?id=29325 and https://bugzilla.redhat.com/show_bug.cgi?id=665887, and might be the same bug as https://bugzilla.kernel.org/show_bug.cgi?id=25572 . Chris Wilson made a patch to allocate i915 memory on a separate slab, and asked me to run with that patch applied. With that, and with slub_debug=FZPU in the kernel command line, I get the attached reports. The first one seems to involve unix sockets, and appeared right after leaving the computer on through the weekend running Vuze the bittorrent client. The rest were invoked with slabinfo -v, and also seem to involve network data. Is this enough evidence to investigate the network subsystem? How should I proceed in investigation of this issue?
