Bug#466229: grub-pc: Fails to boot, hangs with GRUB displayed

[Peter Hicks]

Package: grub-pc
Version: 1.96+20080216-1
Severity: critical
Justification: breaks the whole system

After upgrading from 1.96+20080210-1 to 1.96+20080216-1, my system failed to
boot, hanging at a screen displaying GRUB.  This version also breaks another
system here, which hangs without even displaying anything on the screen.

Reinstalling 1.96+20080210-1 and performing a grub-install /dev/sda fixed
this problem.
