The Teron Boards (and chips) worked poorly enough that the company was put out of business. DMA is basically broken, audio doesnt work (or is not installed) in the majority of the boards and oh yeah, they have a mortality rate that is terrible.

Actually they finally got the onboard sound chips to work and somebody batch-ordered more for the people that didn't get them. Assuming you're not banned from AmigaWorld.net you could have been informed of this.
Also, the DMA thing had to do with the caches not updating automatically when a DMA took place which is just what happened when the classic Amiga did DMAs so is it any wonder that the problems only occured under Linux and not AmigaOS?
The mortality rate is another story, however, and I agree that those CPU modules and cooling fans need improvement as a result. I believe that's ACK Software Controls' first order of business as soon as Dad gets better.
