Hi, 

Im experiencing a kernel bug on making a snapshot, I really like to use 
next3 so i hope it can be fixed. 
>From  what I can see rsync has something to do with it. 

I am using Debian Squeeze on a ProLiant DL380 G5, 
the file system is on top of an LVM volume  on  a multipath MSA2012sa 
device.
