Here are logs when upgrading kernel to 3.19 from 3.13 on Ubuntu 14.04 desktop.

Before rebooting the OS, I dumped kernel modules currently loaded.

I use an USB WIFI adapter on my laptop(rt2800usb), which is important for me, because I can not access to the internet without that module.

dump kernel module loaded on kernel 3.13.0-71.
