Hello,
When I run lvcreate -L1G -n backup -s /dev/gentoo/root to create a snapshot of
my root partition, the process hangs. I can only stop my computer with SysRq
keys. When I restart the computer, the volume seems to have been created but it
is not listed as a snapshot. I have tried LVM 2.02.70 and 2.02.72 and the
problem occur with these 2 versions. I am using udev 160. Does anybody know
what's happening ? With kernel 2.6.34.2, everything works correctly.

Thanks in advance for your help.
