I have a SPARCStation ELC with a pair of DEC RZ55 disks that are
causing my kernel to have problems when they are probed.  I moved
one of them over to my pc532, and had the same problem.  However
the mini-root (with disklabel and kernel) I got to get my ELC up
and running, (Thanks again David!) boots OK.

I got his kernel config, and there's nothing special in there,
however if I build a kernel with the same config file, I get
wonderful things like:

sbus0 at mainbus0 ioaddr 0xf8000000: clock = 20 MHz
dma0 at sbus0 slot 0 offset 0x400000: rev 1+
esp0 at sbus0 slot 0 offset 0x800000 pri 3: ESP100A 20Mhz, target 7
scsibus0 at esp0
probe(esp0:0:0): max sync rate 3.90Mb/s
probe(esp0:0:0): target put in SYNC mode
probe(esp0:0:0): esp0: timed out [ecb 0xf85a58a0 (flags 0x8, dleft 20, stat 2)],
 <state 5, nexus 0xf85a58a0, phase(c 1, p 1), resid 20, msg(q 0,o 0) DMA active>

This is from a kernel SUP on July 8, 1996.  David's kernel was build April 2
if that makes any difference.  Any suggestions?

Many thanks in advance,
