[Bug 1044749] [NEW] kernel panic after upgrade ubuntu server from 10.04 to 12.04

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

After an upgrade from Ubuntu Server 10.04 to 12.04, the system didn't
restart.

Just after (silent) grub I have:
The disk drive for / is not ready yet or not present.
Continue to wait, or Press S to skip mounting or M for manual recovery.

Nothing can be done at this stage (S or M doesn't work)

Then I followed http://ubuntuforums.org/showthread.php?t=1507558 (at the
bottom of the thread), just a bit more complicated as my system is using
LVM(found a nice tuto on how to mount LVM), but finally was able to
follow the procedure:

- I mounted my root partition, chrooted to it
- I fixed all the issues regarding apt dependencies (there was a lot).
- Re-installed linux-image-3.2-29-generic
- update-grub
- grub-install /dev/sda (maybe there I should have used sda1...)

FYI my system is as follow:
sda1 linux partition (small) that seems to contain only grub stuff
sda4 logical
sda5 LVM, my real / partition in my original install

After all of this I get a:
Kernel panic - not syncing: Attemped to kill init!
Pid: 1, comm: run-init Not tainted 3.2.0-29-generic #46-Ubuntu

Then I retried the procedure but before re-installing the kernel, I mounted /dev/sda1 (the one that seems containing grub stuff) on /boot (of my chrooted partition) wondering if it was not needed by grub...
No success.

This server was running the 10.04 for years...

Please any help welcome as this server is the center piece of my home
network.

Thank you in advance,
