Yep. 4.x was perfectly stable on the hardware in question here. The "feature set" of the newer ATA code may be better, but the stability is significantly worse. IMHO "requiring" 3ware cards for drives to work right is such a huge step backwards that for the lower-end server user, and virtually all desktop users, it will basically kill FreeBSD off. -- -- Karl Denninger (karl@denninger.net) Internet Consultant & Kids Rights Activist http://www.denninger.net My home on the net - links to everything I do! http://scubaforum.org Your UNCENSORED place to talk about DIVING! http://genesis3.blogspot.com Musings Of A Sentient Mind
