Comment 11 for bug 268625

Work around:

I've spent the morning hunting all the docs for a work around this one seems to be working:

echo -e '#Intrepid ssb/ndiswrapper workaround, added' `date` '\ninstall ndiswrapper modprobe -r b43 b44 b43legacy ssb; modprobe --ignore-install ndiswrapper $CMDLINE_OPTS; modprobe ssb; modprobe b44;' | sudo tee -a /etc/modprobe.d/ndiswrapper
