Hi

I have just installed Mandrake 10.1, and everything went fine except networking. I know there's nothing wrong with the network card itself since it works under Windows and earlier versions of several Linux distributions.

The installation procedure correctly detects my card and installs the module:

[root@localhost root]# lsmod
Module Size Used by
...
de2104x 18208 0
...

However, eth0 is not activated :

[root@localhost root]# ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1

TX packets:211 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:23340 (22.7 Kb) TX bytes:23340 (22.7 Kb)

but it is known:

[root@localhost root]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:80:AD:A8:53:CD

RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)

although it can not be activated:

[root@localhost root]# ifup eth0

Determining IP information for eth0...
Message from syslogd@localhost at Mon Dec 27 16:38:03 2004 ...
localhost kernel: Disabling IRQ #11

This time I did not activate it at startup, but if I do, the "Disabling IRQ" message comes at that time.

Does anyone know what's wrong, or can give a hint of how I can continue my troubleshooting?

Thanks
Daniel

Try typing more /proc/interrupts to see if any other device is using IRQ # 11. If so, you may have to override the IRQ chosen by the driver.
