I have a dell xps 13 9360 and I installed Ubuntu 17.04.
Everything works and is fine as best as I can tell, but booting up takes nearly 2 full minutes.
If I run dmesg everything seems to be working well until we get to this point:

Please check my posting history. I have paid for computer or technical help multiple times. If you fix this, I will definitely pay you. As you can imagine, having a 2 minute boot time is quite annoying.
