    Ok, this is a real simple fix.  Your driver is calling malloc() without
    either the M_WAITOK or M_NOWAIT flags.  It must call malloc() with one
    or the other.  If it is not using either flag then add M_WAITOK to it.

I know I'm being a bit of a butt-in-ski here, but wouldn't it be the safer, more backwards compatible path to make malloc() internally use the M_WAITOK logic if neither that flag or M_NOWAIT was explicitly set? Otherwise isn't there always the risk that an incoming SW bundle will break upon entering DfBSD space? (Please ignore me if I'm wrong...)
