   Yes, I see this string:

   NetBSD 7.99.30 (CGDDEBUG) #0: Thu Jun 16 19:40:27 BST 2016
           alnsn@neva:/home/alnsn/netbsd-current/clean/src/sys/arch/amd64/compile/obj/CGDDEBUG

   This is the kernel I was running. The disk was initially filled
   with random bits and CGDDEBUG kernel didn't exist back then.

So maybe it did get written, but there's just something funny about
it.  If you pass -v to savecore, can you find what aspect of the dump
savecore doesn't like?
