[Jeroko <jeroko@xxxxxxxxx>]

I get this error on my new Toshiba P50t-C-104, with kernel 4.3. No
monitors attached, just the default laptop screen. I get a black screen
after this message on boot. The only way to boot is to use the
'nomodeset' kernel parameter, but that dissables the intel graphics
card.
