So what is the mistake I made here?
Should I have given a globally unique name as the first argument to DRIVER_=
MODULE()? I didn't see that in the man page, and other examples of pcib dri=
vers apparently get away with it.
I did notice the weird message about "driver already loaded from kernel". I=
wondered if that meant I was dragging in code to the core kernel, that wou=
ld otherwise live in an external module?
Let me know how I can help fix it!
