The problem: people with problems are very vocal, while the users without probs are silent. So will see always lots of complaints, but almost never success stories. I have not any more problems with my ~amd64 system than I had with my ~x86 system. I would even postulate, that I have seen less breakage on ~amd64. -- gentoo-amd64@gentoo.org mailing list
