I've attached the lspci -vv output as well as a tarball of most of
/var/log/installer (except the partman log) if it helps.The motherboard
is an Asus M5A97.
Using ubuntu-bug or apport is a no-go because of the requirement of a
full-blown X and GTK environment - it'd be a pretty great idea if
ubuntu-bug didn't need all that eye candy and had a command line
option...

Title:
reinstall of precise breaks grub with invalid arch independent ELF
magic
Status in “grub2” package in Ubuntu:
Confirmed
Bug description:
I did an over the top install of precise without formatting the drive
to preserve the home partition. I can now not boot the computer and
can't reinstall grub.
ubuntu at ubuntu:~$ mkdir target
ubuntu at ubuntu:~$ sudo mount /dev/sda1 target
ubuntu at ubuntu:~$ ls target/
bin etc lib lost+found proc selinux usr
boot home lib32 media root srv var
cdrom initrd.img lib64 mnt run sys vmlinuz
dev initrd.img.old libnss3.so opt sbin tmp
ubuntu at ubuntu:~$ sudo mount -o bind /proc target/proc
ubuntu at ubuntu:~$ sudo mount -o bind /dev target/dev
ubuntu at ubuntu:~$ sudo mount -o bind /sys target/sys
ubuntu at ubuntu:~$ sudo chroot target
root at ubuntu:/# grub-install /dev/sda
Installation finished. No error reported.
root at ubuntu:/# exit
ubuntu at ubuntu:~$
reboot, same error, grub rescue prompt with invalid arch independent
ELF format.
The computer was installed as 64bit 11.10, upgraded to 12.04 and
updated frequently. I broke unity a bit and decided to try the full
reinstall process from a live USB. The computer is a core i3 laptop,
with a 320GB drive, default partitioning /dev/sda1 is big and all the
data /dev/sda5 is swap. Installing precise 64bit from daily live CD
image.
