Catching up after the holidays ;-) Above chanspec values are invalid. 
0x100e = channel 14/bw 20MHz. The 'iw list' output shows all these 
channels are disabled. So who/what is trying to set these channels. 
Scanning sets the channel in firmware. Is this initiated from hostapd? 
Maybe trying ACS? As these are marked as disabled user-space should not 
use them. What I don't understand is why these pass the cfg80211 layer 
so adding Johannes here.

Arend
