 After looking into this some more, I think the crashes are caused by a
 combination of two issues:
 
 1. NetBSD/amd64 5.2.3 panics when running the ATF tests if the kernel
 is built with "options DIAGNOSTIC".  This issue is not specific to Xen -
 a GENERIC kernel with options DIAGNOSTIC running on the bare metal
 panics, too.
 
 2. The domU kernel in the NetBSD/amd64 5.2.3 release is built with
 "options DIAGNOSTIC".  My understanding is that this option is not
 supposed to be enabled in release builds.
 
 I believe the i386 kernels have the same issues as amd64, and 5.2.3
 is not the only release of NetBSD 5 affected.  "options DEBUG" is
 also incorrectly being set, but that is not the cause of this bug.
 
 My concern when filing this PR was that the panics might be caused by
 some general bug in Xen or the NetBSD/Xen port that could also impact
 more recent NetBSD versions.  Since this appears not to be the case, I
 do not intend to pursue these issues further; those who still have an
 interest in the NetBSD-5 branch are welcome to fix them.
