>Description:

	After making a kernel with "make DEBUG=-g", then
	applying "strip -x" to the result, then "make install",
	and finally booting from that kernel, what happens
	is that savecore, ifconfig, and kvm_mkdb exit on signal 11
	during bootup.  They die within a strcmp in __fdnlist
	trying to look up symbols in the kernel.  They apparently
	seg fault following a bad pointer in the mmap()'ed kernel
	image.

	Apparently, there is some incompatibility with the output
	produced by "make DEBUG=-g; strip -x kernel", and what
	__fdnlist expects to see.

>How-To-Repeat:

	cd /sys/compile/YOURSYS
	make DEBUG=-g
	strip -x kernel
	make install
	reboot
