I've gotten UEFI booting working on some platforms, while other platforms are not working. Specifically, booting on Intel's own motherobards using Intel's own BIOS software (Specifically, the SOX5810J motherboard) does not seem to work. I get the blank screen before the kernel is about to come alive and after grub hands off execution to the kernel. It boots fine with the noefi flag, but without noefi it doesn't work.
I've tried all sorts of kernel flags to try to get some sort of output: earlyprintk, debug=all, loglevel=7, vga=771, etc. However, nothing works -- the system is hung (numlock doesn't cause the LED to turn on/off). Although I suspect this to be a kernel bug, could it be that grub is setting up the video improperly or something? The AMIBIOS boards have some special video mode that uses the gnu unicode font. The intel boards only use the default system font. Any ideas on how to get some sort of output or kernel panic would be appreciated.
