Two same network cards problem
 

I have two realtek 8139 NICs...
System detects only one of them ant that one is working properly. I was thinking that maybe other card is defective so i put only one of them in my system. Separately booth of them work but when i put them booth kernel detects only one of them. I have tried all bios IRQ combinations but i cant fix problem.

Please help me.


Best regards

I do not have the solution, but one suggestion
look into "bonding" ethernet cards. There must instruction/information
on this.

thank you on reply,
nothing happens after bonding

I did not mean to do the bonding but to see if this
technique came with information about kernel module loading
such you could have the 2 cards detected independently

maybe some clues in
modinfo nameofkernelmodule

and
less /usr/src/linux/net...whateverdocthereisonthatmodule

I think you can set irqs via kernel module parameters at boot as well

I have no other suggestions
I find the topic interesting, but am sorry I cannot help more

module is 8139too so how do i set module parameters, my unix knowledge is very basic

look at syntax for at1700: AT1700 driver
http://tldp.org/HOWTO/Module-HOWTO/i...l.html#AEN1555

post content of /etc/modprobe.conf
and /etc/modules

a heavy way would be as root
modprobe -R 8139too
modprobe 8139too io=0x260 irq=5
modprobe 8139too io=0x280 irq=5

for more info
lspci -vv | grep -i ETHER -A8

I do not have the solution, jsut some ideas, not sure how you find the IO
