日志中有两行ACPI MEMORY or I/O RESET_REG.这是因为内核的reboot逻辑是在首次尝试使用acpi进行reboot失败后会再次尝试使用acpi进行reboot；两次尝试均失败后，尝试使用efi进行reboot。efi是通过efi_call从efi system table中调用reset_system服务进行reboot（efi system table中存的是由firmware填写的服务函数地址）。efi_call跳转到rdi对应的函数地址，而宕机时RDI:00000000000000f3说明调用到的是是一个空指针，这也与宕机Code: Bad RIP value.对应上了。
因此，bios出问题的可能性较大，可请bios的同学排查定位。
