  Modified files:
    sys/dev/snp          snp.c 
  Log:
  Do not allow the SNPSTTY ioctl for the snoop device that has a tty
  attached. Otherwise, the snp->snp_tty would be overwritten, while the
  tty line discipline still set to the snpdisc. Then snplwrite() causes
  panic because ttytosnp() cannot find the snp.
