Does anyone net boot NetBSD on sun4c?

I have about a 1 in 10 success rate - with a power cycle required
between attempts....

I've just loaded the 1.2 distribution on my boot server (SunOS 4.1.4 SS5)
and updated /tftboot/boot.sparc.netbsd, the result it not much better
than I had with 1.1

Type  'go' to resume
Type  help  for more information
ok boot net netbsd

power cycle time...

I was curious to see whether the 1.2 kernel could handle the floppy
controller in this SS2 (having it configured in a 1.1 kernel was sure
to hang the machine)...

Booting a Classic looked better...
