We have had an IVECS card in our VAX-11/785 since november 1986. It is
configured to simulate 6 DMF-controllers (48 ports). We had problems
from the very beginning with this card. Sometimes the card rebooted
itself throwing all the users out from the machine. It seems that the
reboot had something to do with the boot of the VMS, because it always
happened 1-2 days after the VMS boot.
We got a new card from Bridge (via Nokia, their representant in
Finland) and then in January the reboot didn't longer occur. Instead
of booting itself it got all locked up. We had to open the unibus
cabinet and boot the Ivecs card with the boot switch on the card.
Sometimes the card was so confused that the switch didn't help, we had
to power the unibus down to make the Ivecs card boot. This card is
also replaced 2 or 3 times.
We have also had the same problems that Yehavi Bourvine mentioned in
his notice: after a while (a couple of days, maybe a week) some of the
ports didn't work anymore, they accepted data and started the
login-process but the user didn't see any output coming from the port.
Bridge told us that it will work ok with 4.5 (that's what we are
running) so the problem is not with VMS.
I checked the actual configuration (sysgen SHOW/CONFIG) with the
configuration VMS wants (sysgen CONFIG) and got the following reults:
(we have already a DMF32-card in the VAX making the total number of
DMFs = 7)

VMS want the CSR of the first DMF on the IVECS card (TXB) to be 760440
and it is configured according to this, but the actual configuration
shows that it is 760454. You can only configure the IVECS CSR
addresses in increments of 40 (octal), 760400, 760440, 760500...
The errorlog shows up some SSYN timeouts on the UNIBUS (we have had 5
of them, the first one from 16-feb-1987) and they look like this:
**************************** ENTRY 9. ****************************

........
so..... is there somebody out there who can give us some hints on what
is the source of our problems with the IVECS card...
