One of my notebooks is a Compaq nc4200 (Mobile Intel 915GM Express). All Ubuntu kernels > 2.6.32-20 don't boot on that machine. Instead I get an error message:
error: unexpectedly disconnected from boot status daemon Begin: Waiting for root file system ...
After some googling I found Bug #574755 in Debians BTS. In this case plymouth had some bug. So I tried to add
i915 modeset=1 to
/etc/initramfs-tools/modules. This made the boot screen complete lack. I saw no output anymore. Second I tried to remove the plymouth-package. After purging it I got the same message again.
I dug a bit further. From my point of view this must be some kind of file system thing. Output from boot:
Begin: Running /scripts/init-premount ... done. Begin: Mounting root file system ... Begin: Running /scripts/local-top ... done. Begin: Waiting for root file system ...`
After some time there is a timeout and a BusyBox shell appears:
(initramfs) Gave up waiting for root device. Common problems: [some hintsregarding root delay and missing modules] ALERT! /dev/disk/by-uuid/(UUID-of-my-sda1) does not exist. Dropping to a shell!
Now I'm out of ideas. What can be the cause of it? How I resolve this issue?
