Problems installing 4.2bsd on a VAX 11/785

[Alessandro Gatteschi]

We are experimenting some problems installing 4.2 on a 11/785.

The configuration is as follows :

	CPU 785
	UDA with a RA81 + RA60
	some DZ11's
	TU77

The first part of the installation ( COPY , boot from the small kernel,
restore of root) was okay.
We have problems when we start moving files from the tape to the disk using
tar.

It seems (and I was told that somewhere in the world had the same problem )
that there are some problems when there is a large amount of UNIBUS transfers.

Is there anyone who fixed this problem or has some advises to go on with the
installation ?

Thanks a lot .
