System: NetBSD xen1.duzan.org 6.1_STABLE NetBSD 6.1_STABLE (XEN3_DOMU) #8: Sat Dec 21 16:22:17 EST 2013 root@nbsd.xnet.duzan.org:/usr/build/netbsd-6/obj/usr/build/netbsd-6/src/sys/arch/amd64/compile/XEN3_DOMU amd64
Architecture: x86_64
Machine: amd64
>Description:
# systat vm

          systat: nlist: can't find following symbols:
          _intrnames
          _eintrnames
          _intrcnt
          _eintrcnt
          _allevents

>How-To-Repeat:
	As described above. Non-Xen works fine, as do other systat
	screens on DOMU. Current as of 2013-12-24 is also fine.
	The kernel is stock XEN3_DOMU with IPSEC and IPSEC_ESP
	enabled in GENERIC.local, and userland was built at the
	same time. Also saw this in a November 27th netbsd-6 branch
	build.
>Fix:
	Unknown. Specifying -N /netbsd, where /netbsd is the same
	as the running DOMU kernel, makes it work properly, so my
	guess is that there is an issue with /dev/ksyms in DOMU
	kernels.
