[Bug 41191] Re: Can't find Volume Group to mount filesystem

[Eric Gonia]

I have the same problem, but it may be a little different issue.

I running Ubuntu Dapper with the latest updates which I think would take
me up to the latest release candidate. I did a fresh install on a dual
boot system. Dual booting Windows XP and Ubuntu. Kernel - 2.6.15-23-386

Hardware is a Dell Laptop C640. Docking station is a Latitude C/Dock II.

Everything is OK if I boot out of the dock. By the way, I installed with
the laptop undocked. When I boot in the dock, I get to the point where
it says "Mounting root file system", and then "Waiting for root file
system". Booting in rescue mode gives "ALERT! /dev/hda2 does not exist.
Dropping to a shell!"

Looking back through the messages, I noticed it is seeing my hard disk
as hde instead of hda, so I rebooted and edited the grub boot string.

I changed root=/dev/hda2 to /dev/hde2 so it now looks like this:
/boot/vmlinuz-2.6.15-23-386 root=/dev/hde2 ro quiet splash

This allows the laptop to boot in the dock and everything works
normally. There does seem to be a longer pause on the "Mounting root
file system", but it does boot.

So my issue seems to be related to what ever is causing ubuntu to see my
hard disk as hde instead of hda when it is in the dock.

What further information do you need.
Should I open a separate bug report?
