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.

Follow-ups

--- Mike Frysinger 2008-12-29 15:22:37

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!
