No hard locks. sure. generally if e crashes, it's ea's (or efl's) fault... and we need to fix it (it could be the fault of a library we depend on though - so it depends). but a system hard lock like jesus is saying.. is a definite driver bug sign. in big neon blinking lights. > In defence of radeon I should say that the only time that I had to look into > which driver was needed and which firmware blob was back when I first > installed Linux on this machine and rolled its first kernel.
