[tulip-bug] Trouble with DS21143

Tue Apr 2 08:43:01 2002

Hi,

I'm having problems similar to what Kapil Khosla reported a few days ago. 
Well, at least the symptoms to the user look the same, all the details are a 
bit different. The machine is a Red hat 7.2 system with a  2.4.9-31 kernel. 
I've been fiddling with the computer for a while now, trying to get the card 
working. I also compiled new tulip driver modules. Below I've attached output 
from /var/log/messages and tulip-diag. Things that seem odd to me:

- Tulip driver says the EEPROM is missing, but tulip-diag seems happy to do a 
EEPROM dump.

- Cardmgr talks about a "UMAX250" card, while the card is branded AmbiCom 
AMB8100 CardBus Ethernet 10/100 TX. Both entries are present in XXX and both 
bind to tulip-driver, so maybe this is just cosmetics.

- Tulip-diag says RX stopped, TX stopped and TX status is "Waiting for Tx to 
finish". DHCP shouts out something and the card hangs?

My (mostly clueless) tweaking here and there is getting me nowhere, any help 
would be greatly appreciated. (Heh, I thought I had it easy: the manufacturer 
prints a penguin on the package and says just to plug the card in. They even 
ship v0.91 tulip.c with the card. Haven't tried that, though. I went straight 
for 0.94...)

Regards,
Antti
