:c014a794 T devsw
:c014a7b0 T cdevsw_add

    c014a79a --- sounds like the same or a similar bug to the one I 
    fixed, where devsw() was being called with rootdev == NODEV (-1)
    and doing a NULL (well -1) pointer dereference.  

    In my case it was related to an assumption at line 203 of vfs_conf.c
    in vfs_mountroot_try() that rootdev had been initialized.  This isn't
    the case for a BOOTP boot.  I do not know about other types of booting.
