I have been having this problem (intermittently) with Ubuntu Server 15.04 and now with 15.10 on my Intel NUC5CPYH for the last 3 months (since I bought it in fact). It only seems to happen when rebooting (never from a cold boot), and it doesn't always happen. I've attached an image of the console output. As my machine is normally headless it is particularly frustrating!
I use LVM but not for the root/system partition, only for /home. My system/root is at /dev/sda1 and formatted with ext4.

I am using latest kernels downloaded from Ubuntu's http:// kernel. ubuntu. com/~kernel- ppa/mainline/ (currently 4.2.5) - but as discussed here it doesn't seem to be a kernel issue.
