xfs freeze nad snapshot problem

Hello

I got following problem:
Trying to make snapshot of lv with xfs filesystem:

# xfs_freeze -f /data
# lvcreate -L20G --snapshot --name snap /dev/VG/LV

and system lock...

(kill -9 doesnt work)

I have to create another session and remowe lockup with:

# xfs_freeze -u /data

If I try to create snapshot without freezeng xfs, it works (bo no cohesion is guaranteed).

kernel: 2.6.9
lvm: 2.00.25
dm: 1.00.19

Anyone can help?
TIA

PS.
This problem is mentioned in:

I have not tried it with 2.6 kernel series and LVM2 userland, but snapshots were (and are) working fine with later 2.4.x kernels and LVM 1 userland.

I wrote xfstests/068 a couple years ago to confirm they were working reliably then.

Hopefully it still works? But 068 may need updating for LVM2?
