I have observed it on internal drives.  If you have two controllers with
different drivers and disks on both then there is no predicting which
driver will load and initiallize first in some cases.  Switching to UUIDs
made the box much more reliable to boot (it was a 50/50 chance it would
boot with the disks in the "right" order and work).
