(Get the code!)
This bug still exists and was reproduced by my attempt to install Ibex on my multiple hard drive system.
I have 6 IDE drives, and one IDE CDROM drive. They are configured: /dev/sda, b, c, and d are hooked to a Promise PCI IDE card, master/slave channel 0, master/slave channel 1 respectively. These are LVM drives, and NOT boot drives. The motherboard's BIOS doesn't see these drives, as they are handled by the Promise IDE's onboard BIOS.
The other two drives are /dev/sde and f. These are both masters on channel 0/1 of the motherboard. The CDROM drive is also attached as a slave of channel 0. The motherboard BIOS sees these drives, and the boot order can be chosen to boot 1st from the CD, then from drive 0 (/dev/sde presumably).
I think I have old GRUB(s) hanging around on one or more of the MBRs from Gutsy Gibbon, etc. The Ibex installer put GRUB on the wrong drive. Going to a GRUB terminal and typing:
root (hd0,0)
find /boot/grub/stage1 (This line gives a file not found error)
find /grub/stage1 (This line works)
setup (hd0)
reboot
Allows me to get past the GRUB Error 2 problem, but then the boot fails as fsck can't access the /dev/sde1 partition... presumably because it thinks it is either busy or already mounted. Looking at it when it drops me into a rescue mode shows it is not mounted, but that the /dev/mapper/pdj.... is associated with that partition. Allowing it to finish booting by (crtl-D escaping from the rescue shell) correcly mounts the /boot partition, but I still can't fsck /dev/sde1.
