IMHO AMD should pay more attention to open driver. Learn from Intel, dudes
I think AMD should learn the lesson from Intel guys who did a really good job with their drivers and consider open driver to be a 1st class citizen. Binary blob is doomed to have a dozens of problems in Linux and will always be very unwelcome and troublesome part of system. So AMD and Nvidia shouldn't get surprised when they lose market share to Intel in this part of market as well. As for, Catalyst has been always causing nasty issues here and there. OTOH opensource driver works very well for me. But it's slower and lacks some features. Most notably, OpenCL and recent OpenGLs.
