PINE64+ Release APs, APs not started

[Henri Hennebert]

Hello,

With FreeBSD 12.0-CURRENT #0 r320599 I can boot normally:

...
Release APs
CPU  0: ARM Cortex-A53 r0p4 affinity:  0
  Instruction Set Attributes 0 = <AES+PMULL,SHA1,SHA2,CRC32>
  Instruction Set Attributes 1 = <0>
          Processor Features 0 = <AdvSIMD,Float,EL3 32,EL2 32,EL1 32,EL0 32>
          Processor Features 1 = <0>
       Memory Model Features 0 = <4k Granule,64k 
Granule,MixedEndian,S/NS Mem,16bit ASID,1TB PA>
       Memory Model Features 1 = <>
              Debug Features 0 = <2 CTX Breakpoints,4 Watchpoints,6 
Breakpoints,PMUv3,Debug v8>
              Debug Features 1 = <0>
          Auxiliary Features 0 = <0>
          Auxiliary Features 1 = <0>
CPU  1: ARM Cortex-A53 r0p4 affinity:  1
CPU  2: ARM Cortex-A53 r0p4 affinity:  2
CPU  3: ARM Cortex-A53 r0p4 affinity:  3
...

With r320869, I get

Release APs
APs not started
   x0: ffff000000977d80
   x1: fffffd000299ba80
   x2:                3

I succeed one time to boot with r321003 but after that I try multiple 
times and get the same error: APs not started

I try r321371 to no avail.

Any idea ?
