troubles mounting ext3 partitions inside a VPS

Hi,

we have some troubles to mount ext3 partitions inside a VPS:
Permissions are ok because mkfs.ext3 and fsck.ext3 work inside the VPS. But if we try a mount we get:

"""
mount /dev/cciss/c0d1p3 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/cciss/c0d1p3,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
"""

an strace says:

"""
mount("/dev/cciss/c0d1p3", "/mnt", "ext3", MS_POSIXACL|MS_ACTIVE|MS_NOUSER|0xec0000, 0) = -1 EINVAL (Invalid argument)
"""

and dmesg in the HOST machine:

"""

Mounting ext2 works without any problems inside the VPS.
Using 2.6.8-022stab050.1-smp
BTW mounting the partition inside the HOST works without any problems, too.

Any suggestions?

cheers,
