[Bug 622865] [NEW] boot problem upgrading to ubuntu 10

[Francesco Tassone]

Public bug reported:

after upgrading from ubuntu 9 to 10, the grub2 loader is not able to boot the kernel, in particular, 
after 30 s a busybox system appears, with messages about giving up to find the device, and /dev/sda6 not found.
from the prompt, I am then able to boot by giving an exec init, altough it says, it does not find the init command.........

I tried to fix in all several ways found on the web:

disabled the uuid root through editing /etc/default/grub
disabled the search string through editing the grub-mksomething_lib
and then update-grub to generate new conf. file.

still same problem occurs.

the problem occurs for all kernels, also older ones.

the uuid etc are all correct
