Well I think once I had a bad udev version which meant the initramfs
didn't work properly, but that wasn't the fault of the UUIDs.

They are part of the filesystem, and no I have never had a problem
with them.  Try running blkid on your devices.

For example:
# blkid /dev/sd*
/dev/sda1: LABEL="Root" UUID="e2dc13ca-f6b1-4f85-859c-e5ce6f4a5c86" SEC_TYPE="ext2" TYPE="ext3"
/dev/sda2: UUID="2iOPQ4-ZRI7-KP4T-OJxg-n2qq-09t8-1Ra8az" TYPE="lvm2pv"
/dev/sdb1: LABEL="ENGBACKUP" UUID="17e68b25-7b04-4025-b5d6-1448c4718a2f" SEC_TYPE="ext2" TYPE="ext3"

# blkid /dev/mapper/*
/dev/mapper/MainVG-Data: LABEL="Data" UUID="f0bce73f-e9ac-41ad-90ed-2525b749be57" SEC_TYPE="ext2" TYPE="ext3"
/dev/mapper/MainVG-Home: LABEL="Home" UUID="020ac4d9-a1fb-4a96-97ad-151c1b761265" SEC_TYPE="ext2" TYPE="ext3"
/dev/mapper/MainVG-Swap: TYPE="swap" LABEL="Swap" UUID="db972dfc-ca38-4a8f-933b-c314ae987748"
