Description Johan Karlsson 2001-05-11 17:52:38 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.2-2 i686)

Description of problem:
My ethernet card was properly detected and setup when I first started
redhat 7.1. Internet worked fine. Then I installed the oss sounddriver and
the network stopped working. I removed the  oss sounddriver and the network
worked again.

After much fiddling I found out that making a /cat/isapnp not only lists my
two isa devices (opt932 soundcard and an ethernet card) but also makes the
network stop working. I believe this might be the same bug that prevents me
from getting sound and network at the same time.

How reproducible:

Steps to Reproduce:
1.cat /proc/isapnp

Actual Results:  netscape, telnet etc. doesn't work.

Expected Results:  Well, netscape should have worked

Eeep... this is scary. I'll investigate on my machine with ISA bus on monday.

Please let me know how it went!

I have noticed that if you start netscape before doing a cat /proc/isapnp you
might be able to use it for a minute or so before the network stops.

I need to go looking for another isapnp card as the card I use for this seems
to have died....
Comment 4 Andreas Hansson 2002-03-14 12:23:00 EST
I have a ne2000 pnp card which is detected fine by pnpdump and isapnp claims to 
configure it but when i cat /proc/isapnp it just displays 0xFF or 0xFFFF for 
everything. When i "ifup eth0" it says there are two cards although I just have 
one card. The card doesn't work properly, and i get errors about interrupt from 
card that isn't active.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
