R7 hangs on boot

[viking]

I cannot event boot R7 in live mode. Kernel panic every time. Screenshot attached.

I have tried to disable secure boot, but there is no difference. I also tried to enable and use legacy boot, but same results.

It's Dell Latitude E7450, with i7-5600U, mSSD and two graphic cards (Intel HD 5500 and nVidia 840M).

I can post inxi -F (or result of whatever command you want) from Fedora later, since Fedora 23 works without any problem on this laptop.
