Knoppix 3.8: booting stops at eth0

[rgruhn]

I am using Knoppix 3.6. and 3.7 without any problems with always the same standard hardware. Booting Knoppix 3.8 stops at recognizing eth0, wainting on DHCP - no way going on. There is a DSL router with DHCP server.
I tried to boot with parameter "expert" but there was no possibility to interact at eth0 or ignore.

Who knows ta solution for this problem?

At the bootup Knoppix 3.8 splash screen, type:
knoppix nodhcp

[rgruhn]

Thnx !
Finally I found this parameter [nodhcp] by myself and used it, but after starting Knoppix I cannot install the network card by hand. The system freezes totally after the input of the correct IP addresses.

What kind of card?

I have the same issue with DEC 21041 Tulip based cards under 2.6.x kernel

Reference: http://www.knoppix.net/forum/viewtopic.php?t=17894

I too have tried to do the nodhcp, rmmod or modprobe -r to remove the module and put a new module for a LAN driver in with out success.

So I am sticking to V3.7 under 2.4.x kernel, and since newer versions of Knoppix will only include 2.6 will just have to wait till what ever the bug is, is resolved.

It is an Intel 21143 fast ethernet PCI adapter.

I 've read the thread you pointed to - may be it is a bug in the 2.6.xx kernel. because I had the same problem with knoppix 3.7 and the 2.6 kernel! I only use the 2.4 and hope the problem will be fixed soon.
Thanks so much.

I think it is but I need to compile some evidence to support this.

Thanks for the info on the card, can you possible post a lspci -v and dmesg with the key parts for reference.

Thanks!

I think my problem is just the same as the well known with a DEC-Chip!
Here is the information:

lspci:

Is this any help, from dmesg and lspci?
Something related to IRQs?

I'm a newbie in this area of linux. Would changing IRQ help? How do I do that in linux?
Thanks.

Some progress thanks to Mepis Forum. Based on
http://www.mepis.org/node/2485?from=...ts_per_page=30
near bottom of page, I tried

rmmod de4x5
modprobe de2104x
ifconfig eth0 up
ifconfig
pump

Now eth0 seems to be up, but still no internet.
dmesg | tail shows eth0: no IPv6 routers present
What next?

[davey]

Hmmm, Ubuntu 5.04 gets eth0 up and internet connection up almost immediately after starting to install. Ubuntu uses de2104x and dhclient (instead of pump).

So would dhclient be better with Knoppix kernel 2.6.x than pump, for my ancient DECchip 21040?
How to do that without installing Knoppix?

Thanks.
