The NVME device pluged in some AMD PCIE root port will resume timeout from s2idle which caused by NVME power CFG lost in the SMU FW restore.This issue can be workaround by using PCIe power set with simple suspend/resume process path. In the onwards ASIC will try do theNVME shutdown save and restore in the SMU FW instead of PCIe power set in the driver.quoted
