Hi,

While trying to install recent master to a couple of striped disks using LVM, I get the following:

dm_target_stripe: Successfully initialized
dm_target_linear: Successfully initialized
disk scheduler: set policy of mapper/main-lv_swap to noop
disk scheduler: set policy of mapper/main-lv_root to noop
panic: assertion "ocnt != 0" failed in prop_object_release at /usr/src/sys/libprop/prop_object.c:1085

Backtrace:
