Boot problem with UUID in Lucid 10.04

[erani]

After an upgrade from 9.10 or after a fresh installation of Kubuntu 10.04 appear a problem with boot the system.

At boot it saying that the root partition with UUID=..... was not found and drop to busybox.
I changed in fstab to not mount partitions by UUID but by device, in my case was /dev/sda2

Sometimes system is booting, sometimes I get error that root partiton /dev/sda2 not found, it seems that root partiton get /dev/sdc2 because when I am booting from flash my HDD is /dev/sdc*

A will try to experiment more and will come with more details if will have it.

After a couple of reboots it seems it's working, I don't know why, but I have added the following in /etc/defaults/grub and made update-grub. The following are:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ahci=off nomodeset reboot=pci"

Today morning it's again fail to boot, the message is:

ALERT! /dev/disk/by-uuid/..... does not exist. Dropping to a shell.

From shell in which system drop me, in /dev/disk/by-uuid exists the link with UUID pointing to ../../sdb2, it's about UUID which system is saying that not found.

I checked /dev/ the file with name sdb2 exists.

I have the same problem.
Except or the fact, that the UUID doesn't exist in /dev/disk/by-uuid.

After a couple of reboots the system is working normally. This seems to happen mostly, if I shutdown my computer (cleanly)
after an apt-get upgrade!

Same problem here. After a clean install of 10.04 ubuntu fails to boot from a raid1 with the message "ALERT! /dev/disk/by-uuid/<uuid of my md0 aka root partition> does not exist. Dropping to a shell.". The directory /dev/disk/by-uuid is not existent in the shell im dropped to afterwards.

Note: the same raid1 that the installed 10.04 can not boot from gets correctly assembled and works just fine with the rescue system of the 10.04 installation medium.
