UEFI boot fails with all of the listed operating systems. Symptoms:
- I get the Fedora/RHEL EFI boot menu, and I let it boot with the default
options.
- I get text on the screen about allocating memory pages for Linux-EFI,
loading VMLINUZ, etc.
- The screen goes empty/black, there's only a cursor blinking, and nothing
happens..
- The boot failed or is stuck with nothing happening. I need to reset the
box.
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
as well.
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.
