Comment 38 for bug 1488719

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.
