Public bug reported:
After upgrading some hardware (MBO, GPU and CPU), the system often does not
boot, drops to busybox shell with the message: dev/disk/by-uuid/.... does not
exist.
I'm having a multi boot ubuntu intrepid, jaunty and karmic, each on it's own
partition and all installations have the same problem. Sometimes i need to
restart the system 3-4 times until it boots succesfully. Old MBO was nvidia
6100/430 chipset and never had any problems. New MBO has AMD 770 + SB710
Chipset, there are 4 SATA disks attached, tried changing the settings in BIOS
'no raid' or 'AHCI' and it didn't help.
I'm attaching a couple of dmesg outputs: two from 9.04 (succesfull and
unsuccesfull), and from 8.10 with succesfull boot.
Googling around didn't help much, there are some hints about some race
condition between SATA and USB, after a couple of failed boots, tried
disconnecting USB mouse and the system booted OK, maybe a coincidence?
