Not really, no. The fact that you're seeing a mode switch proceeding a
blinking cursor makes me think the kernel is probably starting, but you may
be seeing a series of failures after that point.
Ok. earlier I tried enabling the Linux serial console with
"console=ttyS1,115200",
but that didn't show any kernel messages on the SOL.
I wonder if commands like "serial --port=0xf0e0" works with the EFI grub
and if that'd show anything important.. (I can't try right now).

Well, either the bootloader or the kernel (or something after that) is not
succeeding If Windows works in UEFI mode on the machine, then we would still
consider it to be a bug we should fix, even if the firmware fails to comply to
precisely to our previous interpretation of the spec.
I'll try installing Windows aswell.
That being said, I doubt if we're going to have a high degree of
success
debugging this over email.
Yeah.. I'm not very familiar with the EFI stuff yet, so I don't known if/how
serial console stuff is supposed to work, or if it's any different from legacy BIOS
boot..
and why I didn't see anything on the SOL.
Thanks for the help anyway!
