Ah. Ok. I see now. It appears the driver has to be signed by a private
key during the build and, unless you got your own public and private
keys and did the actual signing process, that module probably isn't.
Anyway, I blacklisted bcma now and things are looking much more
promising.
But I'll use it for another 12 hours first just to make sure it actually
works properly now.
Thanks for the tip!
