Probably means for some reason you are now using ide-generic rather than
the native driver for your IDE controller (which would explain it
dropping back to /dev/hda).  Figure out why it isn't loading the correct
driver in the initrd, or why it isn't recognizing your controller (maybe
dmesg has some hint).
