[Bug 496435] Re: upgrades of the grub-pc package can overwrite wrong MBR

 

I encountered this bug today upgrading Kubuntu from a clean 10.04
install to 10.10 using the update-manager tool.  The machine is 32-bit.
It has no SATA controller at all.  It's not a Dell (it's an older Asus-
based dual athlon MP system).  There is only one hard drive in the
system.  There is no other operating system on the machine; just one
bootable partition which has Ubuntu installed. There were no errors
during the install, except that a reboot left me hanging at "error: the
symbol 'grub_xputs' not found" with a grub rescue prompt.

The only odd thing about the drives in this system is that there are two
DVD burners on the on-board ATA controller, there is one ATA-133 drive
attached to a 3Ware 8-port IDE RAID controller (Escalade 7500-8), and I
have /boot set up as a separate partition, with an LVM root.  I came
here due to bug #609280 being marked a dup of this one.

I can run "ls /" at the prompt, and it shows that there is a
grub/normal.mod file visible.  However, when I try to insmod
grub/normal.mod, I get the undefined symbol message from above.

Did Canonical hire the former Gentoo quality assurance team? :)  I
upgraded two (single drive) laptops today as well, and they both had
kernel problems post-reboot.  And now this bug which has been open for a
year?  Really?  Sigh, off to find the rescue disks.  Lemme know if
there's any further information I can contribute which helps fix this.
Or any further poking upstream Debian with a stick I can do.
