Bug#490959: linux-image-2.6.25-2-amd64: upgrade from 2.6.24 to 2.6.25 changes drive identities

[Rutger ter Borg <rutger.terborg@gmail.com>]

Package: linux-image-2.6.25-2-amd64
Version: 2.6.25-6
Severity: important


When upgrading to 2.6.25, the linux kernel re-assigns drive letters with respect to how it is done in 2.6.24.
In my particular case, /dev/sdc is swapped with /dev/sdb. This will make a remote reboot unreliable and/or impossible, parameters
used by the boot loader and fstab must be updated and even then the system keeps complaining about special 
devices which should be normal devices.

This also happened, in reverse order, when upgrading from 2.6.18 to above. 

Nothing is changed in the BIOS. Booting into 2.6.24 says the root file system is on /dev/sdc, booting into 2.6.25 
says the root file system is on /dev/sdb.
