That is not the idea behind DFS. If interference is detected, it is mandatory to back-off from a channel and not retry again for a certain amount of time (half an hour, if memory serves).

    iw phy phy1 info

should show how long channels will not be available for further scanning. Restarting the interface should not make a difference, as the timer must not be reset in that case.

You should really ask yourself, if frequent dropping out of the selected channel doesn't mean there actually *is* interference preventing your routers from using them. This whole DFS thing is there for a reason.
