"noefi" kernel cmdline option didn't help unfortunately.

When booting Fedora 17 x64 there's the GRUB bootloader with graphical background image, 
I let it boot the default entry "Fedora 17", I see it the allocating memory pages, loading VMLINUZ etc, 
and then the display mode / resolution changes, and then there's just blank screen and a cursor blinking.. 

Does that ring any bells? 

I forgot to mention earlier that fedora/rhel works OK using legacy BIOS boot,
so only UEFI is problematic on this box. 

I'm pretty sure this is a Intel firmware bug, but it'd be nice to be able to confirm that somehow..

Thanks for the reply!
