This is an interaction of the rmap vm patch (included in -ac) and the nVidia binary driver. I have run into this myself, tho it doesn't usually cause a lockup for me. (instead, it puts kswapd in the Z state (it aparrently never respawns), and makes shutting down a PITA.))
Mind you, this is a bug in the nVidia driver, not the linux kernel, where it pulls a behaviour that never was really correct before, but did work. This bug truly needs to be reported to nVidia.
Not having that specific kernel tree on my system atm, I can't seem to find the line that is BUG()'ing. But iirc, it's in this set
if (page->buffers) BUG(); if (page->mapping) BUG(); if (!VALID_PAGE(page)) BUG(); if (PageLocked(page)) BUG(); if (PageActive(page)) BUG(); page->flags &= ~((1<<PG_referenced) | (1<<PG_dirty));
and is the (page->mapping) test.
please, check your tree for the correct line (102 of page_alloc.c) to verify this, and then pass it along to nVidia.
