Issues setting channels list for wireless auto channel selection

Installing and Using OpenWrt
1

I am having some trouble configuring a list of channels that can be used when auto selecting the wireless channel. I have set the wireless.radio1.channels option to a certain set of possible channels. But whenever I reload the wireless interface it keeps choosing a channel which is not in this list. The current output of wifi status is:

{
	"radio0": {
		"up": false,
		"pending": false,
		"autostart": true,
		"disabled": true,
		"retry_setup_failed": false,

	},

		]
	}
}

I am running a snapshot build OpenWrt SNAPSHOT, r22665-626c84340d (due to issues with the partition table that were not yet fixed in the latest stable release) on a Netgear WAC124. What is still missing from my configuration for the auto channel selection to respect the channels list?

I played around a bit with the channels list and the behaviour does seem to depend on the channels you include. It seems to be able to auto select one of the lower 5 GHz channels (38 - 50) if they are in the list. With the currently configured list with only the very high channels it doesn't seem to select anything and hangs indefinitely during startup if you choose auto for the channel. If you have a much larger list also including the DFS channels it seems to randomly choose a DFS channel even though it's not in the channels list. Since I was not able to auto select from the channel list I wanted I manually configured a channel for now.
