Subject: RE: rtsx_pci not restoring ASPM state after suspend/resume

Hi James, Bjorn,

The Card reader(10ec:5287) is a combo chip with Ethernet(10ec:8168), we think it is not cause by setting our device config space in idle time.
We dis/enable the ASPM(setting config space) at busy/idle time, it can make our R/W performances well not a work around function
PCI Host and Device setting self config space and do handshaking, we think it does not affect the system
