kern/device.c and https://savannah.gnu.org/bugs/?26834

[Arthur Marsh]

Hi, I rebuilt grub2 from Debian unstable sources with the following 
patch applied and have no longer had to manually remove the "search" 
line in my grub.gfg in order to boot on a hard disk with /boot partition 
visible to the BIOS where the entire disk is bigger than what the BIOS 
recognises.

This *is* a relatively common configuration for old machines with 
replaced hard disks.

Someone suggested posting this patch here. I forget who posted it in 
IRC, but it worked (-:.

There is still one error message about a filesystem with a particular 
UUID not being found, but the boot process is now automatic.

Arthur.
