Hello, I hope someone here can help me out.. I have a new Intel DQ77MK motherboard, based on the Intel Q77 chipset. CPU is Intel Ivy Bridge i7-3770. I'm running the latest BIOS version (0048), and UEFI boot is enabled in the BIOS. I've tried UEFI booting the following operating systems from burned DVDR discs: - Fedora 16 x64 DVD. - Fedora 17 x64 DVD. - Redhat Enterprise Linux (RHEL) 6.3 Server DVD. (Redhat Linux is supposed to be UEFI supported per the motherboard manuals). 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 aswell. Does anyone know how to debug/troubleshoot UEFI boot problems? The motherboard in question has Intel vPro/AMT, so it has SOL, so I could use a serial console, if there's a way to use it with UEFI/bootloader before Linux is started.. Any help is welcome!
