Bug#702395: debian-installer: When booting with EFI, only the first console works



Package: debian-installer
Severity: normal

I just installed a new laptop with the Debian installer rc1.
I put the netinst img raw on a usbkey and boot from it.

First, I boot with the legacy BIOS. Here, the installer works
as always. I can access (with Alt-Fx) to two more consoles
(F2 and F3) and to the log (F4).
As I was using a gpt partition table, my BIOS was complaining
about an invalid partition table (I had to type 'enter' but
then grub-pc loads itself and all was working).

So, I decided to try to boot in UEFI mode. So I use the
installer rc1 from my usbkey again in rescue mode.
And here, only the first console works. When switching to
Alt-Fx x>1, the screen does not change but some glitches
at the top of the screen (the first lines). Comming back
to Alt-F1 remove the glitches and give me hand back.
  I think this is "only" a display problem because I've been
able to type (without anything to see) in the second console
to mount a usbkey to copy a firmware in /lib/firmware (and
creating this directory before). As the wifi driver has been
able to work, it means that my commands have really been
executed.
