>How-To-Repeat:

Configuration:

Xen host: NetBSD-current (3.99.11, XEN0)
Xen guest: NetBSD-current (3.99.11, XENU)

both use FFSv2 with softdeps enabled

configure both as NFS client and server

xen host exports /usr/pkgsrc and /usr/pkgsrc-dist
xen guest exports /usr/pkgsrc-obj

xen host mounts /usr/pkgsrc-obj from xen guest in /usr/pkgsrc-obj
xen guest mounts /usr/pkgsrc and /usr/pkgsrc-dist from xen host in /usr/pkgsrc and /usr/pkgsrc-dist

Ensure that xen host and xen guest have read-write access to each other
via NFS

/etc/mk.conf is this:
DISTDIR=/usr/pkgsrc-dist
WRKOBJDIR=/usr/pkgsrc-obj
PKGVULNDIR=/usr/pkgsrc-obj


Steps to do:

cd /usr/pkgsrc/lang/perl5
make
<kernel panic happens during extracting the tarball>
