Red Hat Bugzilla – Bug 187112
CNet PRO200WL PCI Fast Ethernet card improperly configured
Last modified: 2008-05-06 11:41:08 EDT
Description of problem:
On FC5 fresh install, presence of the CNet PRO200WL PCI Fast Ethernet card
triggers both the tulip and dmfe kernel modules and networking doesn't work.
The IP address gets set correctly by DHCP but network connections (including
host lookups) don't work.
Version-Release number of selected component (if applicable):
How reproducible: Always
Steps to Reproduce:
1. Install CNet PRO200WL network card.
2. Install Fedora Linux Core 5.
3. Boot and attempt any network connection.
Failed hostname lookups.
Linux (via lspci) reports this card as "Davicom Semiconductor, Inc. 21x4x
DEC-Tulip compatible 10/100 Ethernet (rev 31)"
Net searches led to setting pci=noacpi on the grub kernel line, which doesn't
seem to help (or hurt in the end).
To make it work from fresh install and boot (and find out if this is your problem):
lsmod # See if both dmfe and tulip are loaded
Adding "blacklist=tulip" and "alias eth0 dmfe" to /etc/modprobe.conf keeps the
tulip driver from getting loaded and the system works after reboots.
The solution (minus the blacklist) came from:
I had the same problem on an upgrade from FC4. To add to the list of symptoms:
during boot the network initialization acts as if it succeeds, but
"/sbin/ifconfig eth0" shows RX packets:nonzero but always TX packets:0.
On my system the file /etc/modprobe.conf already contained the line "alias eth0
dmfe". Adding the line "blacklist tulip" (no equals sign) fixed the problem.
Thank you for finding this solution.
A new kernel update has been released (Version: 2.6.18-1.2200.fc5)
based upon a new upstream kernel release.
Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
may address this problem.
This bug has been placed in NEEDINFO state.
Due to the large volume of inactive bugs in bugzilla, if this bug is
still in this state in two weeks time, it will be closed.
Should this bug still be relevant after this period, the reporter
can reopen the bug at any time. Any other users on the Cc: list
of this bug can request that the bug be reopened by adding a
comment to the bug.
In the last few updates, some users upgrading from FC4->FC5
have reported that installing a kernel update has left their
systems unbootable. If you have been affected by this problem
please check you only have one version of device-mapper & lvm2
installed. See bug 207474 for further details.
If this bug is a problem preventing you from installing the
release this version is filed against, please see bug 169613.
If this bug has been fixed, but you are now experiencing a different
problem, please file a separate bug for the new problem.
No, the problem has not gone away as of the 2.6.18-1.2200.fc5 kernel. If the
line "blacklist tulip" is removed from /etc/modprobe.conf, the symptoms are the
same as I reported on 2006-04-28 10:28 EST.
Fedora Core 5 is no longer maintained. Is this bug still present in Fedora 7 or
We no longer have a machine with this ethernet interface, so I cannot tell
whether the bug is still present. Sorry.
