Description of problem:
ne compatible pnp ethernet card gets irq 3 attributed just like COM ports 
(irq 3,irq 4) by boot. cat /proc/interrupts doesn't show irq from com 
ports? It seems not possible to influence this behavior. At boot there is 
always put in /etc/sysconfig/hwconf for ISAPNP network card 0x300,3. If 
corresponding with conf.modules than ping works, no other 
machines possible to ping in network. Card works when configured 0x240,5. 
I have to disable eth1, create a eth2 change /etc/sysconfig/hwconf and 
conf.modules for that.

Works well on RH 7.0 on same machine 2.2.17. The only difference is isapnp 
possibility in 2.4.2.

what is the problem? or do I make a configuration mistake.

How reproducible:

Steps to Reproduce:
1.on each boot eth1 gets irq=3 io=0x300

Actual Results:  not possible to run internal network

Expected Results:  access internal network

Problem solved: explanation
- installed Redhat 7.1 from scratch
- made a traditional modules.conf (adding options io and irq for the isapnp 
- did not work and cat /proc/interrupts showed a ne card on irq3 same as com 
port irq3 in boot sequence
- additional I installed isapnp tools what made it more complicated
- reinstalled Redhat 7.1
- set only in modules.conf 'alias eth1 ne'
- rebooted and got automatically probed ne at io=0x240 irq=5
- in /etc/sysconfig/hwconfig the card is still mentioned on io=0x300 irq=5
- connection works

After a week of searching I didn't find a hint in the documentation available. 
The doc mentions isapnp tools and my first modules.conf. Nobody mentions the 
changes in configuration for Linux 2.4.
