Update: I've been able to reproduce the crash using a post merge
kernel (of course, I had to use CONFIG_SLUB since CONFIG_SLAB is
busted) a single time.  Unfortunately, I've not been able to reproduce
it reliably so I can't speak to whether reverting 2143c1965a76 will
fix things.  But it does seem very likely.
