Do you have the bootp options in your kernel? Drew pointed out that
I need these as well as the NFS_ROOT option in my kernel.
options BOOTP # Use BOOTP to obtain IP address/hostname
options BOOTP_NFSROOT # NFS mount root filesystem using BOOTP info
options BOOTP_NFSV3 # Use NFS v3 to NFS mount root
options BOOTP_COMPAT # Workaround for broken bootp daemons.
options BOOTP_WIRED_TO=dc0 # Use interface fxp0 for BOOTP
Also, it turned out that dc0 does not autodetect the media correctly on my
boxes. If you have xp1000's, you will probably need the included patches.
My bootptab finally ended up looking like:
.default.freebsd:\
:sa=147.155.137.1:hd=/scl/boot:bf=netboot:\
:rp="147.155.137.1:/d/fbsd40.alpha/":\
:sm=255.255.254.0:\
:gw=147.155.136.252:\
:hn:ht=ether:vm=rfc1048:
puck:ip=147.155.137.90:ha=0000F871D472:tc=.default.freebsd:
ariel:ip=147.155.137.91:ha=08002B867745:tc=.default.freebsd:
Aside from the Irix 6.5.4 nfs server, things work fine. I can panic it
consistently with a make world though, even if /usr/obj is local..
