I had the exact same problem. I managed to get around it though. Here's what happened on my system.
I created a snapshot of a logical volume, containing my root partition (ext4). The lvcreate command hanged (unkillable), my system broke down and needed a hardware reset to recover. I reinstalled lvm2, udev and dev-mapper related packages to no avail: the problem remained. I found out though that the problem does not arise when creating snapshots of unmounted logical volumes. When creating a snapshot of a mounted logical volume in another volume group, i.e. one without system critical partitions, the lvcreate command also hangs (unkillable), but at least the system remains operational. It turns out that the problem only affects the volume group in which the snapshot is being created. Still, the only way to shut down was with a hardware reset. When I boot into the 2.6.32-23 kernel instead of the 2.6.32-24 kernel the problem is gone and everything works fine. So it seems that this is may be a kernel bug rather than a lvm2 bug. Dunno. I'm just happy that I found this workaround, albeit after many frustrating hours :-). Hopefully this messages will save someone else that time or help some one to fix the bug. Keep up the good work folks.
