Bug#473340: grub-probe: "cannot find a GRUB drive for ...."

[Carlo Fusco]

I can exactly confirm the same bug in my system. I have t2 disks sata,
sda1 that is mount in my home dir and sdb1 that conteins the operating
system. Some time during boot they get inverted (I imagine is a bios
issue) and therefore initiramfs stops and drops me on a shell. Usually
a reboot is enough to fix this problem

 Here some more info.

/boot/grub/device.map.

(hd0)   /dev/sda

grub-probe -t device /

/dev/sdb1

grub-probe -t device /boot

/dev/sdb1

grub-probe -t fs /boot

grub-probe: error: cannot find a GRUB drive for /dev/sdb1.
