I have recently installed ubuntu 16.04 but i am having some trouble with my mouse and keyboard taking a long time to respond on boot. I have uploaded the dmesg output to gist.
When in the grub menu the keyboard works fine. Once ubuntu boots and gets to the login screen i am unable to type or move my mouse for ~30 seconds.
