ipw3945 - cannot access `/sys/bus/pci/drivers/ipw3945/00*/c

[kurtg]

I've been using ipw3945 successfully for 18 months, but I recently had some udev problems with eth0 and may have messed up my wireless configuration. When I want to start the wireless, I do the following:

# /etc/init.d/net.eth1 start
* Starting eth1
* Running preup function [ ok ]
* Configuration not set for eth1 - assuming DHCP
* Bringing up eth1
* dhcp
* network interface eth1 does not exist
* Please verify hardware or kernel module (driver) [ !! ]

and when I attempt to start the ipw3945 daemon I get this:

# /etc/init.d/ipw3945d restart
* Caching service dependencies ... [ ok ]
* Stopping ipw3945d ... [ ok ]
* Starting ipw3945d ...
chown: cannot access `/sys/bus/pci/drivers/ipw3945/00*/cmd': No such file or directory
chmod: cannot access `/sys/bus/pci/drivers/ipw3945/00*/cmd': No such file or directory [ ok ]

So, I'm not sure where to go from here. I'm currently using this kernel:

Linux seeker 2.6.24-gentoo-r5 #3 SMP PREEMPT Tue Apr 22 11:15:38 EDT 2008 i686 Genuine Intel(R) CPU T2500 @ 2.00GHz GenuineIntel GNU/Linux

I'm re-emerged ipw3945d without any differences. Any help welcome.

Had the same problem after a kernel upgrade. Try adding the following code somewhere into your /etc/conf.d/net:

Code: Select all

preup() {
        if [[ ${IFACE} = "eth1" ]]; then
                sleep 3
        fi
        return 0
}

This will give the driver time to initialize.

I had same problem. This error appears to me when I try to compile kernel with Processor Family-->Core 2/newer Xeon option. I have to make it with 'Pentium-pro'.

Hi, first IPW3945 doesn't work at all with the kernel 2.6.24.

You should migrate to the Iwl3945 driver.

If you need help with that, just post
