Yes, can you turn on debug for the interface: ifconfig iwm0 debug
(replace iwm0 with your actual wifi device if it is different).
That will give a lot more output in the dmesg buffer, but also the
results of channel scans and when it is looking for a new bssid to
connect to.
The kernel needs to select a new bssid to connect to, move to it, then
this patch lets wpa_supplicant listen for those changes and react to
them.
