Summary: During boot: WARNING: at fs/sysfs/dir.c:462 _sysfs_add_one

Details:

 

Could be the same issue as this closed one:

  blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=4583

 

but with a Bluetechnix CM-BF548 Board and I DISABLED the SPORT Driver in the Kernel Config already - does not change anything.

I am using SVN Trunk.

This last  "[: not found"  is also a bit strange.

exactly like it says, you cannot register two things with the same name

 

review your kernel configuration and make sure you arent enabling both compat

physmap support and explicit physmap support in your board config

 

--- Dominik Herwald                                          2008-12-30 07:31:26

Ah sorry Mike. Problem Solved!
