We were never able to get any version of freebsd after 8.2 to be stable enough on at91 hardware to ship products. That was after investing a couple hundred hours in trying to track down and fix causes of panics and disk data corruption in freebsd 9, 10, and 11 on our hardware. I never tried 12, because $work hasn't been interested in investing any more resources in such old hardware. I'm not convinced freebsd > 8 is really robust any armv4 or v5 systems, but we do have plenty of reports of "it works for me", so we've been doing what we can to keep it limping along for those folks. Afaik, that community is now down to users of Marvell Kirkwood chips (Sheeva and other *Plug systems). -- Ian
