There are some recent changes that fix problems with b43 hanging the
system at load. To use them, you should get the compat-wireless package
from the Packman repository. If that does not fix your problem, then you
should try the latest kernel (2.6.35-rc3) from the wireless-testing git
tree. If that does not fix the problem, then let us know here, and we will
figure out some additional debugging steps.
