f21 kernel issue
Trying to get fedora21 working with my gaming laptop but after booting from a liveUSB stick it says an error has been detected in the kernel. The "install to hard drive" option doesn't work (nothing happens when you select it) and the entire system hangs to the point where it is unusable (ex: it takes about 10 minutes of waiting to open a terminal).
I am booting in UEFI-native mode and this is a requirement for other operating systems. The video card on the laptop is an nvidia GTX850M.
I managed to get the output of dmesg and found the following when searching for "error":
[ 0.149301] ACPI Error: No handler for Region [EC__] (ffff88022704d090) [EmbeddedControl] (20140724/evregion-163)

What do these errors mean? Is there anything that I can do to get fedora working with this laptop?
That means the nouveau module for the nvida card cannot load the firmware try using compatibility video mode.
How can I use compatibility mode when booting from live USB stick?
