Kernel Bug Tracker – Bug 9336
e100 does not work after boot
Last modified: 2008-03-21 04:41:57 UTC
Most recent kernel where this bug did not occur: unknown
Hardware Environment: GIC68 motherboard
Software Environment: ethtool version 3,
ip utility, iproute2-ss060323,
ifconfig 1.42 (2001-04-13)
Problem Description: e100 did not send or receive packets after boot once
Steps to reproduce: compile e100 as a module and boot with Ethernet cable attached to Telco System’s T5 Compact 10/100/1000 Ethernet Routing Switch.
Running the following commands made packets transmission and reception possible:
ifconfig eth1 down
ifconfig eth1 up
did this work in older kernels? can you try 2.6.24-rc2 or even better, try jgarzik/netdev-2.6 #upstream?
I got a similar Bug 8652 in kernel version 188.8.131.52.
I have not been able to reproduce the bug in kernel version 184.108.40.206.
I read that as "you don't have any more problems". correct?
please close the bugreport if that is the case.
I have not had that problem any more. But I suspect it might be a bug that happens only sometimes.
I meet this problem on my 915gv machine when using 2.6.22 or 2.6.23 kernel,when i ifconfig,only display lo,not eth0. 2.6.21 has no this problem,network can work.
please post your dmesg, lspci -vvv from both 2.6.21 and 2.6.22 so we can see what is different. I can't investigate unless I have some debuggin information.

dmesg while eth1 did not work on Linux 18.104.22.168

dmesg after eth1 worked after ifconfig eth1 down ifconfig eth1 up

Linux configuration file .config
ifconfig eth1 showed UP and RUNNING even though traffic did not work.
The following lines in dmesg look suspicious:
[ 83.017954] Clocksource tsc unstable (delta = 111864067 ns)
[ 83.018930] Time: pit clocksource has been installed.
Yes, that might hit us here. Grmbl. Can you please boot with "nolapic_timer" on the kernel command line ?

*** This bug has been marked as a duplicate of bug 5149 ***
I thought a wake-on-lan fix could fix this bug, too, but it is not necessarily a duplicate.
I think this is related to disabling of IRQs in a driver.
