I just tried to repeat your issue and I get a crash in the credit scheduler!?

(XEN) Xen BUG at sched_credit.c:917
(XEN) ----[ Xen-4.4-unstable  x86_64  debug=y  Tainted:    C ]----
(XEN) CPU:    0
(XEN) RIP:    e008:[<ffff82d08011a30d>] csched_free_vdata+0x9/0x15
(XEN) RFLAGS: 0000000000010202   CONTEXT: hypervisor

If I create a pool with any scheduler other than arinc653, I do not see this
crash, so something is definitely not right.

I am pretty sure that this line in the arinc653 scheduler is the culprit.

    if ( (vc->sched_priv = xmalloc(arinc653_vcpu_t)) == NULL )
