 Hi Paul,
 
 I have changed my local code according your suggestions. If gpio is 
 available in the kernel configuration the kernel compiles and runs fine. 
 If the gpio attachement in kernel configuration is removed however the 
 linker complaining about unresolved symbol gpiobus_print. To be honest I 
 already expected a linker error without NGPIO preprocessor directives. 
 I'm not entirely sure how NetBSD make process is done, but I assume the 
 sys/gpio/gpio.c isn't compiled if not configured.
 I can add the NGPIO conditions again, but doubtful If the additional 
 rescan is still useful.
 
 Best Regards
 
 Stephan
