Bug#586143: grub: Re: boot: Unaligned pointer 4c191bea

2010-06-20 Thread C. Scott Ananian
Package: grub-pc
Version: 1.98+20100614-1
Severity: normal
File: grub

Saw this in grub 1.98+20100614-1.  Booting into a rescue disk, mounting and
chroot'ing to my old system, and running 'grub-install /dev/sda' fixed the
problem.

Please check whether /boot/grub/stage2 existed (assuming you haven't
already upgraded to 1.98+20100617-1, which will offer to remove it for
you if it exists and it detects that you've run grub-install with GRUB 2
at some point).
