[rhgb] Network doesn't receive packets after dhcp, init scripts complete

Description of problem:
Installed Fedora Core Test 3 on an HP OmniBook 4150 which contains a Xircom
ethernet/modem card. Networking does not work, as detailed below. Red Hat 9 on
the same hardware worked.
The hardware was detected during the install, and after booting, the correct
modules load and DHCP succeeds. However, after the system completes booting up,
the network does not work:
- /sbin/ifconfig correctly shows the DHCP-assigned IP, netmask, a small number
of packets sent and received.
- /etc/route -n displays correct-looking output
- pinging the gateway or other machines, (by IP address) returns "Destination
Host Unreachable". And of course no other network applications work.
There are no interesting messages in the system logs. "dmesg" contains:
xircom cardbus adaptor found, registering as eth0, using irq10
xircom_cb: Link status has changed
xircom_cb: Link is 100 mbit
Thinking that perhaps the firewall was to blame, I removed the
/etc/rc5.d/S08iptables symlink, shutdown and rebooted the machine. Nothing
changed - DHCP worked, but nothing after that, just like before.
If (as root) I cd to /etc/init.d and do "./network restart", it shuts down eth0
and loopback, sets network parameters, brings up loopback, and then fails to
bring up interface eth0.
/proc/interrupts shows the following on irq 10 (usb-uhci, Texas Instruments
PCI1225, Texas Instruments PCI1225 (#2), ESS Maestro 2E)
(Should I be seeing the ethernet driver here? Perhaps this is the problem?)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install Fedora Core Test 3 on an HP Omnibook 4150 with a Xircom PCMCIA
2. Choose the DHCP and Firewall Enabled options during install
3. Try to use the network after the install.
Actual Results: DHCP works during boot. After that, networking does not work.
Expected Results: Networking should work :-)
Happy to provide more information or try anything, including kernel patches or
This sounds like a driver problem.
A large bunch of network driver updates are pending for 2094. Give those a shot
when it turns up in rawhide
I tried updating the laptop to the 2.4.22-1.2110.nptl version of the kernel,
which was current as of October 28th, and that didn't help...
I'm experiencing the exact same problem with Fedora Core 1 (kernel
2.4.22-1.2115.nptl). I can also verify that Red Hat 9 worked fine for
me. I have a Dell Inpiron 8100 with a Xircom ethernet/modem card.
I asked for help from the sysadmin at school and after searching for a
while, he found that running
cardctl eject 0
then waiting for a little while and then running
cardctl insert 0
would get the ethernet connection up and running. After he found
this, I went to post a bug to bugzilla, but found this bug already
entered. So, I'm adding the info here.
More info: This doesn't seem to happen on my home network, but it
does happen on the network at school...which seems really odd to me
since I'm using DHCP in both places. Also, at school, I occasionally
have to re-run the above commands again throughout the day. *shrugs*
Oh, and I left off one of the commands above. After the two cardctl
commands, I always have to run an 'ifup eth0'.
More info: Bug 109616 is a duplicate of this bug and says that the bug
can be worked around by removing 'rhgb' from the kernel parameters at
boot. This workaround works for me as well.
