  After further investigation bad commit is :
  
  3430098ae463e31ab16926ac3eb295368a3ca5d9 is the first bad commit
  commit 3430098ae463e31ab16926ac3eb295368a3ca5d9
  Author: Felix Fietkau <nbd@openwrt•org>
  Date:   Sun Oct 10 18:21:52 2010 +0200
  
      ath9k: implement channel utilization stats for survey
  
      Results for the active channel are updated whenever a new survey dump
      is requested, the old data is kept to allow multiple processes to
      make their own channel utilization averages.
      All other channels only contain the data for the last time that the
      hardware was on the channel, i.e. the last scan result or other
      off-channel activity.
      Running a background scan does not clear the data for the active
      channel.
