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.
