Works:
1. point-to-point subinterface to a point-to-point subinterface
2. physical interface to a physical interface
3. mulitpoint subinterface to a multipoint subinterface
4. multipoint subinterface to a physical interface
Doesn't work:
1. point-to-point subinterface to a physical interface
2. point-to-point subinterface to a multipoint subinterface
Basically the issue is with point-to-point interfaces sending point-to-point
IIH's (ISIS hellos) and multipoint or physical interfaces sending LAN IIH's.
There isn't a way to change the hello types.
Also remember that if you're going to run ISIS over frame relay on a
multipoint subinterface or a physical interface you'll need to map clns to
the dlci.

There had been lengthy discussions on this topic not too long ago. I'm sure
you can find what you're looking for from the archives. If I remember
correctly, Brian Dennis posted a good list of what works and what not.
