  1. Intel PROW 3945 Issues, Rebuilt Kernel, New drivers, ifconfig wlan0up No such file or device

    So I tried install the IPW3945 drivers and firmware and daemon with
    slackware 12, from the /extras, It always said that it couldnt find
    the IPW3945 Network Connection when the daemon ran, and dmesg shows
    that IPW3945: Cannot read ipw3945.ucode reason: -2
    Okay so I finally got the rebuild working, and I installed the new
    iwifi drivers and mac80211.
    Then I ran the load script and it showed wlan0, however I run ifconfig
    wlan0 up and i get no such file or directory.
    Also, it doesnt scan with iwlist scan.
    When I do iwconfig, it shows IEEE 80211a, and its the Intel Pro
    Wireless ABG 3945, so I dont know if it will change automatically or
    what, but ive seen peoples iwconfig, and it showed bg.
    I cant do ifconfig wlan0 up, so I cant get it to connect to anything.
    Any ideas why this is?

  2. Re: Intel PROW 3945 Issues, Rebuilt Kernel, New drivers, ifconfigwlan0 up No such file or device

    So after much help from #slackware@freenode, I have realized that
    since I had to do chmod -x rc.udev, to avoid getting the blackscreen
    at bootup after my initial installation, it seems that the firmware is
    having problems loading, and dmesg shows:
    Cannot read microcode reason: -2
    So when udev is ran, I get the blackscreen and cannot do anything
    except hard power off. It has been concluded that it most likely is a
    module that is causing these problems with udev, and not udev itself.
    This has happened with the same microcode error with iwlwifi drivers
    and the old ipw3945 drivers, so it seems obvious that it is not a
    driver issue or firmware issue from a certain set of drivers.

    The iwl-xxx drivers use a separate microcode than the ipw driver.
    Did you install those?

    You need to have:
    /lib/firmware/iwlwifi-3945.ucode

    Yes, thanks, I did install those. The md5sum matches as well.

    So basically I figured out that since udev is -x, I cannot read
    microcode of the ipw3945 card. However udev gives me a blackscreen and
    locks my comp up, so I have to have it -x.
    Running Nvidia geforce go 7950gtx pci x, Ive read others having issues
    in archlinux with geforce and udev, but no solutions.

    A wild guess ... do you have an nvidiafb module.. that maybe udev loads
    automaticaly??

    Or probably it's some other module ... you'll have to investigate this.

    Replying to the list for the OP because I think I remember/know-more
    about what finally fixed the problem. :^)

    The OP's laptop was hard-locking when udev ran. Robby, Fred, and I
    were working on this pretty hard and heavy during the KDE 4 Release
    Party. At first we suspected a module conflict of some sort, and
    quickly banged up a script to test.

    find /lib/modules/$(uname -r) -name "*.ko" | (while read MOD; do
    i=$(basename $MOD .ko)
    echo $i >> /root/mod_log
    sync
    modprobe $i
    done)

    The intention was to locate what module was the last to be loaded
    before the system froze up. Unfortunately, this did not resolve the
    issue. The script went through every module one by one and finally
    completed, all without a single lock-up. This pointed us to a problem
    with Slackware's udev or a kernel bug. Since other distros worked fine
    with the laptop, we dis-missed the idea of a kernel bug.

    Since we didn't want to spend too much time troubleshooting something
    that might have been fixed in -current, we got the OP to install
    - -current from an unofficial iso obtained from slackware.no. When this
    failed to resolve the issue, we felt certain it was a bug in udev.
    Running udev by hand from the shell prompt was successful, but when
    rc.udev was 755, the system would lock-up before booting was completed.

    At a loss of what else to do, we called in PiterPunk for some help. He
    eventually traced the error down to 60-pcmcia.rules. While I am still
    uncertain exactly what was done to fix the problem, Piter informed me
    that when he serialized the udev rules rather than run them in
    parrallel, everything worked properly. This of course, means that
    rc.udev takes much longer to run, but it at least operates properly.

    Hope that helps to explain things to everyone.
