These two lines are the problem:
Nov 17 23:40:15 debian-githin NetworkManager: <warn> /sys/class/net/eth0: couldn't determine device driver; ignoring...
Nov 17 23:40:15 debian-githin NetworkManager: <warn> /sys/class/net/wlan0: couldn't determine device driver; ignoring...
This indicates a problem with either udev or that the kernel network
drivers you're using are buggy. What kinds of devices are the ethernet
card and the wifi card? One thing you can do to figure it out is:
udevadm info --query=all --attribute-walk --path=/sys/class/net/eth0
udevadm info --query=all --attribute-walk --path=/sys/class/net/wlan0
and reply with the results.
