  | I am unable to rewrite the code. Can you send me a patch?

ps: unless you changed the kernel between the #8 and #9 crashes, netbsd.8.gz
can just be a copy of netbsd.9.gz - the file only exists to make sure that 
there's a copy of the kernel binary to match the core dump (in case /netbsd
is changing from boot to boot.)
