  Modified files:
    sys/kern             link_elf.c 
  Log:
  Check to see if the hash table is present in link_elf_lookup_symbol()
  before dereferencing it.  Certain corrupt kernel modules might not have
  a valid hash table, and would cause a kernel panic when they were loaded.
  Instead of panic'ing, the kernel now prints out a warning that it is
  missing the symbol hash table.
