Bug#624550: Shows only grub promt on boot

[Roland Gruber]

Package: grub
Version: 0.97-65
Severity: important

Hi,

since the last grub upgrade in wheezy I always get a black screen with a
command prompt ("grub>") when booting.
After some time I can run the normal grub menu by entering "normal". Then I can
select my kernel and boot up without further problems.

This is quite strange. If I enter "normal" to early then I just get a fresh
command prompt and after some time (minutes) it seems as the command cannot be
used, too. So I run "normal" several times and after a minute or so it gets me
to the boot menu.

Any idea why this happens? Is there anything I can do to debug this?

Thanks in advance.


Best regards

Roland
