FWIW, I'm having similar problems with a DEC3000/300 box I'm trying to
netboot. (It took me a while to figure out that I had to boot "ez0"
instead of "esa0" to get bootp instead of MOP.)
My bootptab looks like this:
modena.plutotech.com: \
:ht=ethernet:ha=08002bbb4eb3: \
:ip=206.168.67.197:sm=255.255.255.128: \
:sa=206.168.67.172:bf=netboot:rp=/b/modena: \
:vm=rfc10248
I get through the first part of the kernel boot, and then I get this
(copied by hand, I'm not using a serial console):
Mounting root from nfs:subway:/b/modena
no such device 'modena'
setroobyname failed
panic: nfs_mountroot: socreate(0000): 43
The stack trace is:
Debugger()
panic()
nfs_mountroot()
nfs_mount()
vfs_mountroot_try()
vfs_mountroot()
mi_startup()
locorestart()
I may try to track this down tomorrow. It seems like it should be
solveable. BTW, I'm running with -current as of ~February 12th, I think,
and I'm netbooting (bootp, tftp and NFS) off a FreeBSD/alpha box.
