eth0 not working..

Shioni · 03-29-2006, 03:02 AM

Hi!
I have a strange problem. I'm running Slackware 10.2. I used netconfig to set IP, gateway etc.. It's strange that I can't even ping the gateway. The card seems to work and when I do ifconfig eth0, everything looks like working.. any ideas please? thank you!

1. Did you check the cable?
2. Did you ping to localhost (ping localhost) or own IP ?
3. After configure IP and other set and restart network , did you check dmesg?
4. How about network POWER and ACT leds ? It is blinking ?

I think , you can find some error or warning message on "/var/log/message", if you have problems on network.

1. Yes
2. Yes
3. /etc/rc.d/rc.inet1 restart; dmesg

Anybody...?

dmoorhouse · 03-30-2006, 05:26 PM

i'd have to say that you have an IRQ conflict. Not sure if there is an easy way in slack to adjust the irq but you can set it in your modules config...I can't remember the details on how to do it off hand, sorry.

<c0132f12>] __report_bad_irq+0x22/0x90
...
Disabling IRQ #3

after this point it looks like your nic goes offline.

Try another nic, remove other not-needed hardware, turn off parallel/serial ports in bios etc... these can mitigate your computers irq usage and free up some resources.

ERBRMN · 03-30-2006, 09:11 PM

I thinking it is IRQ problem (like dmoorhouse).

Did you check interrupts list. Following sample is for my case.

[root@CAP3 sysconfig]# cat /proc/interrupts
CPU0
.............
10: 70881 XT-PIC uhci_hcd:usb5, yenta, wifi2, eth0
.............

**********************

Also you can find IRQ information after command "ifconfig".

I think system must be auto setup IRQ.
But ...
To change IRQ of network card using Network tools.
Did you change the network card ?

Can you also mention whether this was working with other distros and only not working with Slack ? And any more details about your machine will also help

Thanks! I Have a SIS 900-Basted PCI Fast Ethernet Adapter. I have ACER-Aspire 5000 Laptop. The card is working in Knoppix! I'm going to check /proc/interupts and ifconfig IRQ..

Shioni · 03-31-2006, 06:10 AM

cat /etc/interupts

Hi Shioni,

I guessed your problem as soon as I saw your notebook model

I have an Acer Aspire 3000 model and I have the same problem. The solution for you is to pass the following two kernel parameters :

noapic nolapic

My sample kernel boot is :

kernel /boot/vmlinuz-2.6.11-1.1369_FC4 ro root=LABEL=/ rhgb quiet noapic nolapic

Your card will work in Knoppix, PCLinuxOS etc which pass these parameters by default. Slack, Fedora etc don't do it, so you have to append it to your lilo/grub file. Newer kernels(2.6.15) dont have this problem, though.

Shioni · 04-01-2006, 03:35 AM

Thanks! But for some reason, didn't work for me.. so I try to boot with irqpoll, and everything works now!
