log to file from kext

I have been trying to get my kext to log to an arbitrary logfile, and
have been experiencing an unending stream of kernel panics with no
success. I started using VOP_LOOKUP directly on the rootvnode with no
luck, and have since been trying namei() without any luck. A code
snippet follows of where I stand right now (a stripped down and
simplified version of my intentions), and I would appreciate any help!
Thanks, I have tried almost endless permutations of what I perceive
to be the possibilities and all have failed...

   int error;
   size_t size;
   struct nameidata ndp;
   const char pathBuf[]="/logKext";
   char * kpathBuf;

   MALLOC(kpathBuf,char *,16,M_NAMEI,M_WAITOK);
   copyinstr(pathBuf,kpathBuf,16,&size);

   NDINIT(&ndp,CREATE,FOLLOW,UIO_SYSSPACE,kpathBuf,current_proc());
  
   error = namei(&ndp);
   if (error)
    printf("namei returns %u\n",error);<!-- ~MESSAGE_AFTER~ -->

You are not supposed to write to disk from a kext. This is a FAQ on the
darwin development list, and everytime people say don't do it. I
believe it IS possible, but you need to have superpowers. You might
check the list archives.<!-- ~MESSAGE_AFTER~ -->
