From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98) 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 127.0.0.1 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: Always Steps to Reproduce: 1.on each boot eth1 gets irq=3 io=0x300 2. 3. Actual Results: not possible to run internal network Expected Results: access internal network Additional info:
Problem solved: explanation - installed Redhat 7.1 from scratch - made a traditional modules.conf (adding options io and irq for the isapnp card) - 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.
