Hmm. So it definitely seems to be the hand-over.
Does this patch make any difference? When we unregister the old
framebuffer, we still leave it in the registered_fb array, which
looks wrong. But it would also be interesting to hear if setting
CONFIG_SLUB_DEBUG_ON or CONFIG_DEBUG_PAGEALLOC makes any difference
(they'd help detect accesses to free'd data structures).
