I can't seem to get a Sparc ELC to boot via NFS from my Linux box.
I've followed every step in the installation instructions but now I seem
to be stuck.

The output on the ELC reads:

Boot device: /sbus/le@0,c00000    File and args: netbsd -s
ea00
>> NetBSD/sparc Secondary Boot, Revision 1.7
>> (pk@flambard, Mon May 11 09:43:48 MEST 1998)
boot: client IP address: 192.168.1.11
boot: client name: lechuck
Can't open network device `/sbus/le@0,c00000'
open: netbsd: Unknown error: code 72
device[/sbus/le@0,c00000]:

What does this mean? Why can't the network device be opened when that
obviously was perfectly possible seconds earlier?
