about pcie-hot-plug on aarch64

Hello, We run Openstack Stein on arm. It runs nova-compute(use libvirt as virt driver) on arm host. We found when built with disks (use ceph rbd) on arm hosts, the vm can not attach all disk correctly. For example, built with six disks, the vm may attach three disks. No obvious error can be fond in nova-compute, libvirt. We compare aarch64 and x86, find when detach disk, the dmesg of the vm's os is different. May be the pciehg parameter is different? Did anyone met the problem? Or some suggestions? x86: Nothing at all aarch64: Sep 29 15:28:55 * kernel: pciehp 0000:00:01.5:pcie004: Slot(0-5): Attention button pressed Sep 29 15:28:55 * kernel: pciehp 0000:00:01.5:pcie004: Slot(0-5): Powering off due to button press Sep 29 15:29:00 * kernel: pciehp 0000:00:01.5:pcie004: Slot(0-5): Attention button pressed Sep 29 15:29:00 * kernel: pciehp 0000:00:01.5:pcie004: Slot(0-5): Button cancel Sep 29 15:29:00 * kernel: pciehp 0000:00:01.5:pcie004: Slot(0-5): Action canceled due to button press Sep 29 15:29:07 * kernel: pciehp 0000:00:01.5:pcie004: Slot(0-5): Attention button pressed Sep 29 15:29:07 * kernel: pciehp 0000:00:01.5:pcie004: Slot(0-5): Powering off due to button press Sep 29 15:29:13 * kernel: pciehp 0000:00:01.5:pcie004: Slot(0-5): Link Up Sep 29 15:29:16 * kernel: pciehp 0000:00:01.5:pcie004: Failed to check link status Sep 29 15:29:18 * kernel: pciehp 0000:00:01.6:pcie004: Slot(0-6): Attention button pressed Sep 29 15:29:18 * kernel: pciehp 0000:00:01.6:pcie004: Slot(0-6): Powering off due to button press Sep 29 15:29:23 * kernel: pciehp 0000:00:01.6:pcie004: Slot(0-6): Attention button pressed Sep 29 15:29:23 * kernel: pciehp 0000:00:01.6:pcie004: Slot(0-6): Button cancel Sep 29 15:29:23 * kernel: pciehp 0000:00:01.6:pcie004: Slot(0-6): Action canceled due to button press Sep 29 15:29:30 * kernel: pciehp 0000:00:01.6:pcie004: Slot(0-6): Attention button pressed Sep 29 15:29:30 * kernel: pciehp 0000:00:01.6:pcie004: Slot(0-6): Powering off due to button press Sep 29 15:29:36 * kernel: pciehp 0000:00:01.6:pcie004: Slot(0-6): Link Up Sep 29 15:29:39 * kernel: pciehp 0000:00:01.6:pcie004: Failed to check link status Sep 29 15:29:39 * kernel: pciehp 0000:00:01.7:pcie004: Slot(0-7): Attention button pressed Sep 29 15:29:39 * kernel: pciehp 0000:00:01.7:pcie004: Slot(0-7): Powering off due to button press Sep 29 15:29:45 * kernel: pciehp 0000:00:01.7:pcie004: Slot(0-7): Attention button pressed Sep 29 15:29:45 * kernel: pciehp 0000:00:01.7:pcie004: Slot(0-7): Button cancel Sep 29 15:29:45 * kernel: pciehp 0000:00:01.7:pcie004: Slot(0-7): Action canceled due to button press Sep 29 15:29:52 * kernel: pciehp 0000:00:01.7:pcie004: Slot(0-7): Attention button pressed Sep 29 15:29:52 * kernel: pciehp 0000:00:01.7:pcie004: Slot(0-7): Powering off due to button press Sep 29 15:29:58 * kernel: pciehp 0000:00:01.7:pcie004: Slot(0-7): Link Up Sep 29 15:30:01 * kernel: pciehp 0000:00:02.0:pcie004: Slot(0-8): Attention button pressed Sep 29 15:30:01 * kernel: pciehp 0000:00:02.0:pcie004: Slot(0-8): Powering off due to button press
