[comp.sys.att] 3b15/NI5 board

john@polyof.UUCP ( John Buck ) (01/21/89)

We've been experiencing some problems with our 3B15 running WIN/3B: Rel 2.1
and AT&T 10BASE5 Rel 1.1.

System config:
	3b15 -- 16 MB memory
	IOA -- with 4 ADLI
	IOA -- with 3 ADLI
	3 - 340MB IDC
	1 - LARKII
	1600BPI 9-track tape
	NI5 board
	Current firmware to allow System V Rel 3.1.1 to run.
	OS == Sys 5, Rel 3.1.1

NI5 has interrupt prio level 4 (as per boot instructions)

Now, the problems:
	The network will be running, say, a telnet, or ftp.
When another telnet/ftp session is requested VIA THE ETHERNET (NI5),
the NI5 board shuts itself down.  (netstat -i indicates en0* )
If you:
sh /etc/rc0.d/K76win3b
/usr/ni/bin/nistop
sleep 2
/usr/ni/lib/niinit -s
/usr/ni/bin/niinfo
sh /etc/rc2.d/S86win3b

this sometimes succeeds in restarting the board, often it says:
"A system PANIC would result if the board were restarted: reboot the
system to restart the NI5 board" (paraphrased).

The other problem (which could be related) is:
if you telnet TO the 3b15 from another host, you have to often
"force" output to be printed to the screen by pressing keys.
That is, you may get a login:
but after you type your login name, it doesnt say Password until you
strike a key.  This "output-delay" is kept the whole time you are logged
in.  If you type "ls", you must type several chars during the ls output
to keep it going.

Sounds to me like ALL the problems could be related to the NI5 board not
properly handling interrupts or not properly queuing IO requests to
the NI5 board.

Does anyone know anything about the NI5 on a 3B15 under S5R3.1.1?

BTW -- we have WIN/3B: Rel 2.1 (Sys 5, Rel 3.2) on our 3b2/600's and
it works fine (relatively speaking).  That is to say, the boards never
hang, nor do we experience the output-delay.

Thanks
