temporary failure in name resolution Net stops working

pele_smk

When I first boot into gentoo. I have net access for about a minute. If I try and ping something I'm fine. If I try to emerge something small I'm fine. Once I try to emerge xfree or something similar I get internet connection for about 20 seconds then all is lost. I can no longer ping any computers or anything until i restart my computer. I have a fine internet connection when I boot from teh livecd. My computer specs are as follows

Amd64
using gentoo-dev-sources
nforce3
My internet connection is dhcp.

here is the rout -n and cat /etc/resolv.conf I have to type this by hand so cut me some slack If I mispell something. Numbers will be correct for sure though.

#route-n
Destination Gateway Genmas Glags Metric Ref Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0

0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0

#cat /etc/resolv.conf

What NIC are you using? Can you post your lspci and lsmod output? Also what does your /etc/conf.d/net look like?

pele_smk · Posted: Tue Mar 09, 2004 2:05 am Post subject: here is lsmod

I don't have net access through gentoo so I have to copy these by hands

#lsmod
usb
bcm5700
tg3

My netcard is a gigabit broadcomm. Originally I had the tiger3 built into the kernel, so i tried using the bcm5700, but I'm getting the same problem with no net access. here is the post from my /etc/conf.d/net

# /etc/conf.d/net:
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/conf.d/net,v 1.7 2002/11/18 19:39:22 azarah Exp $

# Global config file for net.* rc-scripts

# This is basically the ifconfig argument without the ifconfig $iface
#
#iface_eth0="192.168.0.2 broadcast 192.168.0.255 netmask 255.255.255.0"
#iface_eth1="207.170.82.202 broadcast 207.0.255.255 netmask 255.255.0.0"

# For DHCP set iface_eth? to "dhcp"
# For passing options to dhcpcd use dhcpcd_eth?
#
iface_eth0="dhcp"
#dhcpcd_eth0="..."

# For adding aliases to a interface
#
#alias_eth0="192.168.0.3 192.168.0.4"

# NB: The next is only used for aliases.
#
# To add a custom netmask/broadcast address to created aliases,
# uncomment and change accordingly. Leave commented to assign
# defaults for that interface.
#
#broadcast_eth0="192.168.0.255 192.168.0.255"
#netmask_eth0="255.255.255.0 255.255.255.0"

# For setting the default gateway
#
#gateway="eth0/192.168.0.1"

I get the exact same behaviour on my nforce 3 chipset as well. One interface drops out after a minute or so, the other lasts half an hour or so. Everything works perfectly up to this point and then nothing whatsoever.

It sounds like a driver problem, did you try a different driver? Maybe use a more generic driver like tulip to see if you can get your NIC up longer.

I have the bcm5700 set up to auto load, and it acts the same way. I'm gonna give it a try with reloading the eth0 with what you said and see if it's any more reliable.

How can I unload the eth0 module and reload it? I'm using modprobe -r bcm5700 then trying to reload it with modprobe -i bcm5700 but it is unsuccessful. It shows up in lsmod, but when I try to connect to the net I don't have a connection still. I tried killall dhcpcd eth0 but it doesn't come back succesfully. Takes about a minute and doesn't get anything.

I had the same problem and I've found how to fix it. I had to disable APIC support by adding noapic after the Grub entry. My network interfaces now stay on.

great!! I'll try when i get home. I'm at school right now. I do remember seeing something about "Are you running some type of weird power mode" in my dmesg. And its right after loading acpi support, so I think you have a fix there. I sure hope so I can't wait to try it. THanks

I had the same message

Uh? NMI returned a value of 3d
Are you running some kind of strange powersaving mode?

That went away with the noapic switch added.
