root partition with xfs fails to boot correctly

[Tilman Sauerbeck <tilman.sauerbeck@xxxxxx>]

Hi all,
I have converted all of my partitions to XFS expect the root partition.
I did the following to get a XFS based root partition:
-did a exact copy on a second hdd
-changed the root entry in /etc/lilo.conf
-ran lilo
-updated /etc/fstab

According to the FAQ one can use XFS on a root partition with LILO when
LILO is installed in the MBR, which is the case here. 

But when I want to boot with the XFS root partition, I get a bunch of
errors:
the system boots, and I get a login, but many services fail etc. I can
try to get a more specific description of the errors.

I am absolutely sure the copy is an exact one and I just don't know what
I could have forgotten to consider :(

I am using Kernel 2.4.5-xfs from www.markybob.com/xfsboot. The rest of
my XFS partitions work flawlessly.
btw: System is Debian testing/woody, LILO is version 21.7.5-1.

Any ideas?

Thanks in advance,
Tilman
