I had a similar problem which I originally reported as a kernel issue. After 2.6.17-7 (8 and 9) the system would not boot with the error:
Begin: Waiting for root file system My /etc/fstab shows: # /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 # /dev/sda10 -- converted during upgrade to edgy UUID=67f18326-0ffc-4835-9de5-67d173f6ca84 / ext3 defaults,errors=remount-ro 0 1 # /dev/sda5 -- converted during upgrade to edgy UUID=2aed16dc-cfb2-49c7-b656-ae238b383997 /media/sda5 ext3 defaults 0 2 # /dev/sda6 -- converted during upgrade to edgy UUID=f8048a1c-68e7-4f26-9d6e-0e43de790488 /media/sda6 ext3 defaults 0 2 # /dev/sda7 -- converted during upgrade to edgy UUID=2f0175ef-bd42-41e2-8e32-c92a155da5ab /media/sda7 ext3 defaults 0 2 # /dev/sda9 -- converted during upgrade to edgy UUID=2854cb27-da6e-44bd-ba7c-18879b5621e3 /media/sda9 ext3 defaults 0 2 # /dev/sdb5 -- converted during upgrade to edgy UUID=6707952b-349c-4cc4-96e4-34147b25930d /media/sdb5 ext3 defaults 0 2 # /dev/sda8 -- converted during upgrade to edgy UUID=fb837170-93eb-45bf-a8e5-6b7e8f0f4d06 none swap sw 0 0 /dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0 But in /boot/grub/menu.lst the relevant boot line showed: /boot/vmlinuz-2.6.17-9-generic root=/dev/sda10 ro If I replaced this with the "right" root location according to /etc/fstab i.e. with /boot/vmlinuz-2.6.17-9-generic root=UUID=67f18326-0ffc-4835-9de5-67d173f6ca84 ro then the system booted without problem. It seems that in upgrading from dapper the filesystem or partition information in /etc/fstab has been changed but this change has not been reflected in the grub entry. Following a suggestion by Ben Collins I removed kopt lines in /boot/grub/menu.lst and ran grub-update. This had the effect of replacing root=/dev/sda10 with root=/dev/hda1 which was veru strange and this also did not help the system boot. I think this is a major bug because I installed a standard dapper and then did a standard upgrade to edgy and the sytem did not boot. -- [Edgy] Wrong boot disk parameter since 2.6.17-7 https://launchpad.net/bugs/61578 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
