I'm experiencing major problems getting our ethernet running in the following
configuration. We have a VAX 11/785, running ULTRIX 3.1. The dmz and dmf0
are DEC dm{f,z}'s, while dmf1 through dmf14 are on an ABLE Computer Inc. dmf
emulation board. If I configure the kernel with only 11 ABLE dmf emulation
modules, the ethernet works without a hitch. Once the twelveth module is added,
I get 5 "dmfdbint" messages on reload, immediately following the string "DECNET
started", and prior to the string saying the circuit is up. We recently
upgraded from ULTRIX 1.2, but we didn't have an ethernet controller on this
machine at that time, so I don't know if the problem pre-existed. Any insight
on this would be greatly appreciated.

My recollection is that the Ultrix SPD claims that no more than 10 of a particular interface type can be configured. This may have to do with the configuration parameters used for the BINARY.vax modules, in which case you probably start stomping over somebody else's data area when you go beyond the pre-configured limit. If this is so, I'm not sure there's an elegant solution w/o source... -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@uunet.uu.net Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)

Sorry for having to repost this. We lost some news in the process of
switching our primary news feed site. On 17-Oct I posted a query about
the possibility of too many dmf devices causing the ethernet to hang.
The only symptoms are, that we can configure a V3.1 kernel with 11 (ABLE
Computer) dmf's, and everything works fine. Once I configure a kernel
with 12, I get 5 "dmfdbint" messages upon reload, and the ethernet is no
longer functional. DECNET reports the circuit as being up, but now
/etc/dnet_check fails, (where it worked before). Rlogin also fails, where
it also worked before. If anyone had any ideas on this, or any information
about the cause of the "dmfdbinit's", could you mail them to me? Thanks.
