Subject: Re: [Xen-devel] Re: kernel BUG at mm/swapfile.c:2527! [was 3.0.0 Xen pv guest - BUG: Unable to handle]

We've discovered a way to reproduce this quite easily!  Fire up a guest, run eatmem with 1M and enough threads to not OOM.

http://www.theshore.net/~caker/uml/patches/utils/eatmem.c

On a 1G guest: ./eatmem 1M 900
