Hello,

I have just installed FC6 on this Dell B130, the installer seemed to detect the onboard wired NIC during install (and a knoppix distro 3.8.x detected it too while I was resizing my XP partition.)

It seems it has detected both the wired and the wireless network interfaces.

In the GUI Network Configuration tool, it shows
eth0 as Ethernet (wired) with mac xxx:59:56
eth1 as Wireless with mac xxx:BD8

This jives with how Windows XP recognizes the mac addresses for the respective interfaces. And it also jives with the contents of /etc/sysconfig/network-scripts/ifcfg-eth*. The wired interface works in XP, I'm unable to test the wifi interface in my current environment.

"ifup" on either interface fails.

Here's where things get weird.
"ifconfig -a" shows eth1 present with mac xxx:BD8 (the mac I expect from the wireless interface) eth0 (the wired interfce) is not present.

If I do "ifup eth0" (the wired interface) I get what appears to be a message from iwconfig:
Error for wireless request "Set Encode" (8B2A) :
SET failed on device eth0 : No such device
Determining IP information for eth0... failed

I would expect to see this failure when attempting to bring up a wireless interface.

When I try to bring up eth1, I get the infamous:
Determining IP information for eth1... failed; no link present. Check cable?

I wonder if this has something to do with how redhat/fedora uses their net config gui tool to create symlink for devices/profiles? But yet, the mac addresses seem correct in the config files in /etc/sysconfig

I am also wondering why eth0 does not appear in the output of "ifconfig -a"

"lspci" shows both the BCM4401 (wired) and the BCM4318 (wireless) interfaces.

"lsmod | grep b44" shows:
b44 32973 0
mii 9665 1 b44

(Should the "Used By" column not be 0 in that first row?)

/etc/modprobe.conf maps eth0 to b44 and eth1 to bcm43xx

Any thoughts on what is going on here?

Thanks for any help

Perhaps this is more help:


The is_wireless_device function of /etc/sysconfig/network-script/network-functions is returning that eth0 is a wireless device because it greps "iwconfig eth0" for the string "no wireless extensions".

But I notice my output of "iwconfig eth0" is "eth0 No such device". If I change ti to grep for this, it fails still and I see in /var/log/messages
dhclient: Bind socket to interface: No such device

Does "No such device" explain why I am not seeing this interface in the "ifconfig -a" output? Is there an additional module I need to modprobe?

I found this:
http://lists.debian.org/debian-user/.../msg00412.html

Though that kernel is a bit older and it's a different distro,
it suggests stopping network, rmmod b44
Then modprobe b44 and ifup again.

I noticed while doing this, in /var/log/messages:

ACP: PCI interrupt 0000:02:00.0[A] -> GSI 18 (level, low) IRQ 19
b44: 0000:02:00.0: No usable DMA configuration, aborting.
ACP: PCI interrupt for device 0000:02:00.0 disabled.
b44: probe of 0000:02:00.0 failed with error -5

I believe this is the bug I am seeing

https://bugzilla.redhat.com/bugzilla....cgi?id=208242

Is there a way to back out to a "non xen" kernel and still have FC6 (Zon) function properly?
