Is the rtsx_usb_ms device attached to an xHCI controller? How is the hang during resume related to the actions of the xhci-hcd driver? (You'll probably need to enable dynamic debugging for xhci-hcd and use a network console to get the answer.) If this problem really is related to xhci-hcd, have you tried bringing it to the attention of the xhci-hcd maintainer? Are you using the most up-to-date version of the kernel? xhci-hcd is still getting fixes at a very high rate.
