I really haven't the foggiest where to look :-(  I don't actually
believe that it's a spinlock problem; that would explain pages getting
substituted for other pages, in whole or in part, but you showed at
least one example where a page was just overwritten with garbage.
That looks more like a memory-stomp problem (again, assuming that it's
software) and so could be anywhere.

Are you using any off-the-beaten-track code (contrib modules,
non-btree indexes, non-mainstream data types)?  That stuff is less
well debugged than the mainstream ...
