When I boot Fedora 9 with a stock 2.7.26.25 32-bit-PAE kernel, it's
hanging forever in the WP test.  I'm running current xen-unstable
1d7221667204.

Another kernel (I think non-PAE this time) complained that the WP test
failed (ie, supervisor was allowed to write to a RO page without fault).

The previous version of Xen I tried (only a couple of days ago), crashed
with "(XEN) Assertion 'v->arch.paging.mode' failed at multi.c:4069" when
starting the same domain, but I'm not sure if it got to the same point.
