NFS服务无法启动，表现为exportfs -r阶段卡住 #23393
Description
请填写以下信息.
Please fill in the following information.
Install ENV: (You can find it in the boot interface.)
- DMI: 华擎（ASRock） B560M
- CPU: 11400
- NIC: (pid & vid)
RR version: (You can find it in the update menu.)
- RR: 25.12.1
- addons:
- modules:
- lkms: prod
DSM:

- version: 7.3.2-86009
Issue:
实体机，SA6400，内核为custom，nfs服务无法开启，无论nfs选择V3还是V4，页面体现为点击应用后超时没反应，root账户执行systemctl start nfs-server也是卡住。进一步观察到是执行exportfs -r的时候卡住，手动执行命令也卡住，并且通过kill 无法中止exportfs -r的执行。如需提供其他日志还请回复，感谢。
