libi2c: Claiming driver slot failed

[芮正新]

Hi Nick，
  rtems_io_register_driver return 5 means RTEMS_TOO_MANY, no major number available.  
  Do you change CONFIGURE_MAXIMUM_DRIVERS to a suitable value?

Thanks & Best regards,
Rui Zhengxin

Hi guys,

When I boot an MVME3100 (PowerPC) off the ticker sample application, I get an error message "libi2c: Claiming driver slot failed (rtems status code 5)".

Complete boot log:
