It's just that > x86_64 isn't as old as i386 to have as many of them. But give it time. It will always fundamentally always have less bugs and quirks than i386 because it's much younger. Modern x86 is significantly different than traditional x86 and in the old days hardware wasn't really tested for the now modern interfaces, so they tended to have a lot of bugs and quirks. -Andi
