I can reproduce this too with 2.6.15-26-386 #1 PREEMPT.

Recovery is simple, the device mapped just gets all out of sync. Rejig the devices and remove the snapshot and reboot. eg:

mv /dev/mapper/vg_sys-lv_vmware /dev/mapper/vg_sys-lv_vmware_snap ;
mv /dev/mapper/vg_sys-lv_vmware-real /dev/mapper/vg_sys-lv_vmware;
fsck /dev/mapper/vg_sys-lv_vmware;
lvremove /dev/vg_sys/lv_vmware_snap;
touch /forcefsck;
reboot;

I think its related to my bug https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.17/+bug/71567
