    Do you think you could make a concise list of disk/controller makers
    who play nice (publish their specs), and/or produce hardware that
    tends to work well (or perhaps "didn't make writing support for
    major PITA")? Outright recommendations might cause trouble under US
    law FAIK, but buying hardware has always been sort of an adventure
    I've seen recommendations (in the form of code comments, commit
    messages, mailing list posts from relevant people, etc) against ASUS
    motherboards, VIA [almost-anything], Realtek network cards etc, and
    collecting relevant information is a time consuming task.

    If you can share your experience, I'll use that as a base for
    a FreeBSD-friendly Hardware Buyer's Guide, and maintain that.

If you cc me or remove the list(s) completely I'll most likely ignore
your message.    see
