Bug Description
booting the latest pi3 image from http://
with monitor/kbd attached but without any network cable shows an oops on the screen when console-conf initializes networking (which tries to also bring up wlan0) this oops does not show when a network cable is plugged in and the network can be configured correctly.
sadly the first user creation relies on having network available, so it is a bit hard to get dmesg output when not having a login.
paolo asked for the used cmdline:
ogra@pi3:~$ cat /proc/cmdline
8250.nr_uarts=1 dma.dmachans=0x7f35 bcm2708_

With today image (04-Oct-2016 - b99626f36cddae8 72e43ef692c4b1b 9f ubuntu- core-16- pi3.img. xz) i'm unable to reproduce it:
1) on first boot, it reaches the config screen, i correctly insert my wifi SSID and password, but when it tries to associate to my wifi it generically fails but i don't get any particular kernel msg anywhere (nothing on ttl serial nor screen)
then i pull the plug and reboot the board
2) on second boot it reaches the config screen again, but the wifi details are already filled in, the board is associated and it has an ip (i double checked this on the AP too), but when i tell it to apply the config and move to the next step, it generically fails again and on the ttl serial i see these messages:

but no traces of an oops.
Now i'll try this kernel / boot firmware / etc on a classic image to see if it works there and if i get any of the above errors.
Question: how do i install and run the 'netconfig' (i think that's the name of the software we run on boot to configure the board) on a classic image?
