I have very similar problem with Intrepid on Dell PowerEdge 1550 with 2 SCSI disks with RAID1 and LVM. /boot partition is also mirrored, but without LVM. After booting kernel 2.6.27-7-generic I can see the following error message:
ALERT! /dev/mapper/horus-root does not exist, Dropping to the shell! Fortunately workaround with rootdelay=90 works for me. Thanks for that!
