Bug#586143: Doesn't boot: Unaligned pointer 4c191bea

[Andreas Jacob]

Hi Colin

Could it be that grub-install, or your patched debug version did
remove the stage2 file? When I execute a grub-install, it seems to
touch or to rewrite almost all files under /boot/grub. May be it also
deletes the stage2 file?

Unfortunately i have no backup from /boot where i can look if these
file were there before. But I did the grub update within a
safe-upgrade, shuted down my laptop, an 2 hours later on rebooting
there was the described behaviour. Meanwhile it's impossible for me to
reproduce the error.

As i can read here, some other people have also no stage2 file but the
same behavior. This couldn't be contretemps.

Cheers Andreas
