 |
|
Hi,
I got some problems with my network card. I performed a stage1 installation and everything works just fine. But as I tried to boot from harddisk I realised that my network card couldn't be found anymore. While booting up I got some error messages like:
| Code: | SIOCSIFNETMASK: No such device
eth0: Unknown interface: No such device |
I have a 3COM card (3c905B TX) and a 2.6.8.1 Kernel. I already activated 3COM support for 3c59x/900 Series network cards in my Kernel (menuconfig). And I also tried to load 3c59x module (autoload) but the problem still persists. |

You can't have it both ways - is it built in or a module ?
You need the 3c59x module for almost all 100mbit 3Com cards.

| Well, I have tried both. First as built in and then as a module. It's all the same: unknown interface. |

no_name,
Show us the lspci output.
You either don't have the NIC you think you do or you have been building the wrong thing.

NeddySeagoon,
there is no lspci on my system (command not found) but I'm quite sure that it is the right NIC since I read the printing on the card itself. |

to get lspci.
We mean it 
But if you're absolutely sure, then try disabling ACPI and APIC on boot - these are known to cause weird problems from time to time.

no_name,
The 3c509B can have several chip sets, depending on what it says on the top of the large black IC in the card, you need either
the 3c59x or 3c50x driver.
See this page http://support.3com.com/infodeli/inotes/techtran/5a96_5ea.htm
Since you have tried one, give the other a shot.
lspci is on the liveCD too.

I had this happen to me and all that was wrong was that I had a bad ethernet cable. I struggled with it for days before I figured this out. 
Sometimes the fancy ones with the rubber that goes around the head and covers up the tiny plastic lever (hope this makes sense) don't work with linux drivers for eth0 (reason is totally beyond me). Get a really plain one.

You mean a molded connector.

Reason is simple - it is very hard to see whether they are broken.
Meaning it probably is.

OK, I found a solution, which is still dissatisfactory. It is working proberly if I enter: but I want to load it automatically during boot up!!
As I already mentioned, it can't find the eth0 device if it is built in the kernel or loaded as module (/etc/modules.autoload.d/kernel-2.6). |

| To have it load during boot, add '3c59x' to /etc/modules.autoload.d/kernel-2.6. |

Well, the wierd thing would be that such cables would work with the same computer booted into windows but not in linux.
