I upgraded from 10.10 to 11.04 (kernel 2.6.38-9) and now Ubuntu won't fully boot. I get this message:
Gave up waiting for root device. Common problems: - Boot args (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough?) - Check root= (did the system wait for the right device?) - Missing modules (cat /proc/modules; ls /dev) ALERT! /dev/mapper/isw_jhdfjbgej_Volume01 does not exist. Dropping to a shell!
Which resulted in falling back to a BusyBox shell.
If I do
ls -l /dev/mapper I get:
isw_jhdfjbgej_Volume0 -> ../dm-0 isw_jhdfjbgej_Volume0p1 -> ../dm-1 isw_jhdfjbgej_Volume0p5 -> ../dm-2
I tried booting with an older kernel (2.6.35-28) and that worked (except for x because the nvidia drivers weren't build) and did
ls -l /dev/mapper and I got:
isw_jhdfjbgej_Volume0 -> ../dm-0 isw_jhdfjbgej_Volume01 -> ../dm-1 # my ext4 partition isw_jhdfjbgej_Volume05 -> ../dm-2 # my swap partition
sudo apt-get purge linux-image-2.6.38-9-common and then reinstalled
nvidia-common for 2.6.35-28 (dkms rebuild the module). Then when I rebooted into 2.6.35-28 I got the same
/dev/mapper/isw_jhdfjbgej_Volume01 error that I got with 2.6.38-9.
