关掉所有phy后，对SAS/SATA盘开phy，其他未开phy的SATA盘会打印‘wait phyup timeout, issuing link reset’

【标题描述】关掉所有phy后，对SAS/SATA盘开phy，其他未开phy的SATA盘会打印‘wait phyup timeout, issuing link reset’
【环境信息】
1） 鲲鹏920
软件信息：
[root@localhost 0000:b4:02.0]# cat /etc/euleros-latest
eulerversion=EulerOS_Server_V200R008C00SPC300B630
compiletime=2019-12-27-10-58-38
kernelversion=4.19.36-vhulk1907.1.0.h619
[root@localhost 0000:b4:02.0]# uname -a
Linux localhost.localdomain 4.19.36-vhulk1907.1.0.h619.eulerosv2r8.aarch64 #1 SMP Mon Jul 22 00:00:00 UTC 2019 aarch64 aarch64 aarch64 GNU/Linux
如果有特殊组网，请提供网络拓扑图
【问题复现步骤】
1、对所有盘关phy
2、对其中一块盘开phy
出现概率(必现)
【预期结果】
开phy的盘重新接入，其他关闭的phy不会有动作。
【实际结果】
其他关闭的phy，对应sata盘报phyup link timeout。
【附件信息】

如下：
对phy0/phy2/phy3关phy后， 再对phy0开phy。
