>Environment:
System: NetBSD lyssa 1.2G NetBSD 1.2G (LYSSA) #2: Sun Oct 19 23:22:12 MEST 1997 tron@lyssa:/src/allsrc/sys/arch/i386/compile/LYSSA i386

>Description:
A kernel based on 971015 sources can't handle more than 5 Virtual Filesystem
loadable kernel modules.

>How-To-Repeat:
Try to load 6 VFS LKMs.

>Fix:
[This patch will make it possible to load 16 VFS LKMs. That will be enough
 for a while but it might be necessary to increase the reserved space in
 future.]
