>Description:
Using GRUB2 to multiboot a Netbsd kernel brings the following warning:

[ Kernel symbol table invalid! ]

I think this is the same problem as described in 
http://mail-index.netbsd.org/port-i386/2010/01/05/msg001720.html
which happens with NetBSD's own loader when using the 'multiboot' command.

A possible fix has been mentionned in 
http://mail-index.netbsd.org/port-i386/2010/01/14/msg001777.html
but has not been commited or pulled down to the netbsd-5 branch, to the best of 
my knowledge.
>How-To-Repeat:
From Grub2 prompt:

insmod ufs2
set root=(hd0,1)
multiboot /netbsd
boot
