I installed Fedora21 (also tried updating the packages) but my system doesn't boot at all when in "Switchable" mode in BIOS.
The only way to have a successful boot is to use the VESA driver (nomodeset), or using the "Discrete" BIOS vga mode.
You can find the journal log attached, in contains useful call traces.
I am available to help with the debugging of this issue ;)
