Docker Daemon初始化挂起：Go栈轨迹解读及环境问题求助

问题背景 #

Docker daemon在启用EBS加密的AWS环境中启动时出现挂起，无法完成初始化。以下是捕获到的Go语言栈轨迹，请求协助解读；同时我查阅v24.0.5版本的Moby源码后，认为挂起前最后执行的代码是daemon/info_unix.go第48行，需要确认该判断是否正确。目前正在排查问题以完善相关Issue，目标是让Docker daemon能在该环境下正常启动。

关键疑问 #

我认为挂起前执行的最后一行Moby代码是v24.0.5版本中的daemon/info_unix.go第48行，请问这个解读是否正确？
