It looks like Linux kernel doesn't get started at all.. so it could be a UEFI
firmware or a bootloader problem.
I'm actually expecting this is an Intel BIOS/UEFI firmware bug, because I've
seen reports about UEFI boot problems on other Intel 7-series chipset
Does anyone know how to debug/troubleshoot UEFI boot problems?
The fact that the cursor is blinking is a bit strange; if grub has attempted
to boot the kernel, that's unexpected. Nevertheless, one thing to try is
to add "noefi" to the kernel command line. If it gets farther, that's an
indication that we're hitting a kernel bug.
