Has this write caching always been present, or was it introduced by CAM? If you're referring to the community of all freebsd users, I think your statement is reasonable. If you are referring to the community of CAM users, that is an extremely small subset of freebsd's installed base, so expecting serious problems introduced in CAM to have all cropped up now is not reasonable. Please note that nothing in this post should be construed as critical to the CAM team. It's a huge undertaking and all signs are that it will be a very beneficial addition to freebsd.
