DMA transfers to and from the SD card stall for 10 seconds and run into timeout on RTS5260 card readers after ASPM was enabled. Adding a short msleep after disabling ASPM fixes the issue on several Dell Precision 7530/7540 systems I tested. This function is only called when waking up after the chip went into power-save after not transferring data for a few seconds. The added msleep does therefore not change anything in data transfer speed or induce any excessive waiting while data transfers are running, or the chip is sleeping. Only the transition from sleep to active is affected.
