Hello
I have exactly same behavior yesterday on this netbook. I suppose the
problem is with the graphical mode which grub is trying to initialize.
The graphics chipset is Poulsbo - it is even wrong handled by xorg
(i mean out of the box) so maybe grub have also problems with it.
After installation i chroot again to the installed system and commented
out line:
GRUB_TERMINAL=console
in /etc/default/grub
after this i of course did update-grub
and voilla! - after reboot everything is ok :)
graphical interface is ugly to me - i am preferring text-mode grub
regards,
