/dev/hda2->/dev/sda2

The new box booted correctly with the old disk.
Loading the necessary modules to be able to access SATA drive (ata_piix.ko).
When I tried to move my PV to a new partition using
pvmove /dev/hda2
I got kernel panic. After reseting I have complitly lost my VG.

What did I wrong?

I forgot to say that my root partition was on the VG I tried to move to the 
new disk.
Did this cause the problem?
