eth0: Tx hung, 7 vs. 0.

Thu Sep 23 12:43:08 1999

Hello...

I thought I would post this here before the l-l list...

I've just jumped from Linux 2.3.11 to Linux 2.3.18ac8, to try out the
new tulip.c v0.91m.

I'm have a couple of problems, but I need suggestions on just this
first one, and then I'll work on the rest.  First, my situation:

H/W Configuration:

Ziatech 5521 with two on-board Tulip 21143's, Tx interface.  eth0 and
eth1
Znyx 414 or something: quad Tulip 21143, Tx (copper) interface. eth2 -
eth5
Osicom dual Tulip (not sure what kind) 100Base Fx. eth6 and eth7

Previously:

Linux 2.3.11, with tulip.c:v0.91 4/14/99 as a module

I was able to use the on-board tulip interfaces without any problems:
ifconfig up down, all around.  No issues.  The quad board I had to be
less free with.

I wasn't able to get the Fx board going easily, but I didn't spend
much time on it.

The tulip driver _would_ recognize all 8 tulip chips, and assign
logical names to them, eg eth0 - eth7.

Currently:

Linux 2.3.18ac8 ==> tulip.c:v0.91m 9/15/99, as a module

Problem:

I cannot use eth0- I get the following repeating error:

> Sep 23 11:54:45 probe2 kernel: eth0: Tx hung, 7 vs. 0. 

When I take the _same_ cable, and move it over to the (also on-board)
eth1 port, things work just fine, I can ifconfig the interface, telnet
to it, etc. Everything appears as normal.

I've never had the experience of the two port behaving differently:
they're the same chips, same interfaces, on the same processor.

So what gives? Suggestions?

Thanks for any help....
