    Ok, I did in a fresh ubuntu install. I installed backports modules and b43-fwcutter like your frist post. after this i remove b43 and ssb and load b43 again and this is my dmesg.

    Ok. It seems like ssb is the problem. Try running
    Code:
    echo "blacklist ssb" | sudo tee -a /etc/modprobe.d/blacklist-ssb.conf
    and rebooting and see if it works. If you want to reverse this, simply delete /etc/modprobe.d/blacklist.ssb.conf

    Is anybody else noticing that, with the b43 driver, the wireless disconnects a lot? It happens to me when I'm downloading something for too long.

    Chenxiaolong,

    Had a chance to make a remastersys permanent usb boot with Ubuntu 9.10. Definitely take the two blacklist items out of your process: wl and ssb. They will keep the b43 from working.

    My new HP Mini 311 is now very solid with Ubuntu 9.10. Runs very nice in both managed mode and under monitor/injection modes.

    Used ws2-tcl (http://forum.aircrack-ng.org/index.php?topic=3734.00) to crack WEP from a long distance in 80 seconds.

    b43 under Ubuntu 9.10 seems to be very effective (Tx and Rc). And, downloading (question from your post) seems fine without the blacklist.

    So, using linux-backports-modules-jaunty without blacklisting b43 and ssb works perfectly? Could you try downloading a large file like the Ubuntu live CD to make sure? Whenever I try downloading a large file and the speed is over 650kpbs, the wireless card disconnects (that is, with the blacklists).

    Sorry, but I have changed wifi card to an atheros from asus eee 900 and works very well. Thanks for all guys but I couldn't wait because I test all ways with the same result, the DMA error.

    Thaks a lot.

    Use only the following command:

    sudo apt-get install linux-backports-modules-karmic b43-fwcutter

    and your downloading will be fine

    and aircrack-ng will also be fine

    You mentioned jaunty in your post....that should be karmic.

    I got the exact same dmesg (or at least the part about the fatal DMA error) until I tried to remove the b43 module, and then my dmesg looked like:

    Hi Jekshadow...and Rusty,

    Please go here first:

    http://linuxwireless.org/en/users/Drivers/b43

    And read it thru.

    Can you post the o/s you are using and the ID of your wireless? If you are using an older 0/s linux kernel that may be your problem. You need 2.6.31 and Ubuntu or Xubuntu 9.10 for example.

    Have you tried Ubuntu 9.10 with the one xterminal command? "sudo apt-get install linux-backports-modules-karmic b43-fwcutter"

    Also, there are many discussions on different web sites if you google on "b43 DMA error". It appears they were using the older kernel and a different process.

    I'm using the 2.6.31 kernel with the latest updates and my wifi card's PCI ID is 14e4:4315. I am using Ubunu 9.10, I freshly installed it a few days after karmic came out and have been updating once every few days. I did try installing the drivers + firmware from source and via repos (removed both between) and both gave the same DMA error.
