HURRAAHHH SUCCESSSS - 10 hours later and still streaming internet without any disconnects or errors! Seems that auto fall back to PIO doesnt work yet, but we can force pio from a config file in etc/modprobe, with the compat wireless pack.
The compat wireless in ubuntu lucid (linux backports wireless) seems to crash my computer, so I compiled mine from scratch. This fix worked for me on 2.6.32 kernel on Ubuntu Karmic, For those that also want the fix heres a short guide. Go to: http://linuxwireless.org/en/users/Download and follow their guide to compile and install the newest bleeding edge compat-wireless-2.6 Go to: http://linuxwireless.org/en/users/Drivers/b43 and follow their guide to obtain the newest firmware (ie the "4.178.10.4" version from openwrt), if you don't have it already Once installed, update initramfs with sudo update-initramfs -vuk all Finally make a file called b43 to force pio from /etc/modprobe.d with the command: echo "options b43 pio=1" > ~/b43.conf && sudo mv ~/b43.conf /etc/modprobe.d/ ** Tags added: karmic ** Tags removed: regression-potential ** Description changed: + **Fix/workaround available inside compat-wireless package. Please see + Post 31** + After enabling the free "Broadcom B43 wireless driver" in Lucid Netbook, I get this in kern.log: Jan 2 23:13:40 morris kernel: [ 344.513384] b43-phy0: Controller restarted Jan 2 23:13:40 morris kernel: [ 344.525432] b43-phy0 ERROR: Fatal DMA error: 0x00000400, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000 Jan 2 23:13:40 morris kernel: [ 344.525462] b43-phy0: Controller RESET (DMA error) ...
