This is extremely unhelpful. I wonder what you consider a "proper place" for a udev blacklist if not udev itself. Just closing a valid bug report is a poor decision. Then please also close https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=711350 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=714401
