Mike,
I normally use my old config file but because I'm jumping quite a few kernel releases I decided to start from scratch.
I did some more investigating this morning and this is what I found.....
1. The SCC driver not appearing in 2.6.25.4 is due to ISA not being selected - my oversight.
2. In kernel 2.6.25.1 ISA is preslected, and all ax25 is preselected as modules
3. In kernel 2.6.25.4 ISA is not preslected and all ax25 is not preselected
Looks like there has been some serious culling of unessential drivers between 2.6.25.1 and 2.6.25.4. Takes me back to 2.0.x kernels.
