Versatec downs UNIBUS under 4.3bsd

[system at asuvax.UUCP]

We recently upgraded from 4.2 to 4.3 on our VAX 780 and have not been
able to get the versatec to run correctly.  When the versatec starts to
print, the system will respond with :

	uba0: uba error sr=3000002<UBSTO> fmer=0 fubar=760514
	uba0: uba error sr=7000002<UBSTO> fmer=0 fubar=760100
	uba0: uba error sr=7000002<UBSTO> fmer=0 fubar=760104
	uba0: uba error sr=7000002<UBSTO> fmer=0 fubar=760100
	uba0: too many zero vectors (5001 in <2 sec)
		IPL 0x15
		cnfgr: 2000<UBIC>  Adapter Code: 0x28
		sr: 7000002<UBSTO>
		dcr: 8010028 (MIC OK)
	uba0: reset dz0 dz1 dz2 dz3 vp0 lp0 dmf0 dmf1 dmf2 dmf3

This will knock lp0, the dz's, and the dmf's offline, but vp0 will continue
to print.  We moved vp0 to our second unibus and it knocks the our uda and
disk drives offline.  In both cases, we have to hard crash the machine and
reboot with the versatec turned off.  If I boot under our old 4.2 disk, the
versatec runs fine.  Has anyone run into this problem or have a fix?
