The same here. Original install: ubuntu gnome 16.04. root fs: btrfs After upgrading to 16.10 all new (4.8) kernels hanging up with this message. Tried with 4.9.0-rc4, the problem still exists. Boots correctly with kernel 4.4.0-43
"Uncommenting #GRUB_TERMINAL=console fixed it." - for me it has not solved the problem.

Found Bug #1547559, saw this comment by Jason Straight. "Stumbled across this today while searching for a fix for a PC running 16.04 that this is happening on. I don't understand why, but editing /etc/default/grub to uncomment the line for graphical terminal fixed it. What that has to do with mounting root I don't know, but that was certainly the fix." "Uncommenting #GRUB_TERMINAL=console fixed it." Yes, it does. Not sure if this is related or not so new bug.
