 I have some suspicion this is related to the following code:
 
 sys/uvm/uvm_device.c:217-219
 
                 /* Note: both calls may allocate memory and sleep. */
                 udv = kmem_alloc(sizeof(*udv), KM_SLEEP);
                 uvm_obj_init(&udv->u_obj, &uvm_deviceops, true, 1);
 
 I believe kmem_alloc should be tested but is not.
 
 Sorry if this is unrelated.
