It's an educated guess. I suppose it could be -mm breakage.

I sent Andrew a patch which tightens up some debug checking, and
that is likely to be causing your BUGs.

The mm/swap.c hunk from git 8519fb30e438f8088b71a94a7d5a660a814d3872
is the mystery fix (the mm.h hunk is already in there).

I suppose you'd better verify that -mm works fine with the patch as
well, when you get time.
