Need help: 3Com Ethernet Board with ULTIRX 1.2

[Paul Marsh]

We recently installed Ultrix 1.2 on our VAX 785, which was running 4.2bsd.
After changing  autoconf.c  to look at non-mass storage peripherals before
looking at mass storage peripherials, we booted the new kernel and got the
following errors:

	ecprobe:  cannot reserve uba addresses
	uda0 at uba0 csr 172150 vec 4, ipl 15
	failed to initialize step3: sa fffa4a0uda500 failed to init
	failed to initialize step3: sa fffa4a0uda500 failed to init
	mba0 at address 0x20010000
	mt0 at mba0 drive 0
	mu0 at mt0 slave 0
	panic: iinit

The ecprobe message is generated after a failed call to the routine  ubamem.
The 4.2 code and the Ultrix code appear to be basically the same.  Can anyone
tell me what might have changed with Ultrix to cause this to break?  Any
ideas will be very much appreciated.  Thanks in advance.
