I have u-boot up and running on a MPC860T-FADS eval board, but it is extremely unstable... are there active FADS developers using this board currently?

I guess you see just what many people experienced on the FADS: the board itself is unstable.

I am in the process of getting a 866ADS - are those any better, or is that just a daughter board for the FADS?

also, here are the minor patches for the FADS; im not sure why the original config file calls for max flash banks 4, when only 1 is (apparently) supported:
